Add macOS with Apple Silicon support

[ainame]

Background

I created this PR to this fork instead of upstream that's not likely to merge PRs like westonplatter#96, westonplatter#99 and westonplatter#100 and release a new version anytime soon.

I fixed extconf.rb as per the title for modern macOS support.

What's changed?

This PR has two parts -

• Support include/lib paths for dependencies installed via Homebrew
• Overwrite the latest config.sub/guess to have build tools recognise macOS with Apple Silicon (the ones bundled with pHash were created 2011 and M1 Mac didn't exist 😇)
  • Reverted the change applied for pHash-0.9.6.tar.gz config.guess,config.subを最新化 #2

Approach for config.sub/guess

When I was working on this fix, I didn't realise there is #2 got merged already. Because I still got the error like this below.

 checking for /etc/SuSErelease... no
 checking build system type... Invalid configuration `aarch64-apple-darwin24.5.0': machine `aarch64-apple' not recognized
 configure: error: /bin/sh ./config.sub aarch64-apple-darwin24.5.0 failed
 *** ../../../../ext/phashion_ext/extconf.rb failed ***
 Could not create Makefile due to some reason, probably lack of necessary
 libraries and/or headers.  Check the mkmf.log file for more details.  You may
 need configuration options.

This PR title says config.sub and guess were updated but it looks like only config.guess was updated.

% tar -xvf ext/phashion_ext/pHash-0.9.6.tar.gz
% ls -lah pHash-0.9.6/config*

 -rwxr-xr-x@ 1 satoshi.namai.01.ts  staff    33K  2 Aug  2011 pHash-0.9.6/config.sub. # <= 2nd Aug 2011 (Not Updated 🤔 )
 -rwxr-xr-x@ 1 satoshi.namai.01.ts  staff   583K 23 Apr  2013 pHash-0.9.6/configure
 -rw-r--r--@ 1 satoshi.namai.01.ts  staff   7.9K 23 Apr  2013 pHash-0.9.6/configure.ac

I went with different approach that we keep the original tar ball but overwrite config.sub/guess in extconf.rb. You can see the changes without tar -xvf and it will be easier to update pHash's version. Does this approach make sense? Let me know. I can change to the original approach squeezing config.sub/guess files to the tar ball.

Testing

• rake compile, rake test passed on macOS 15.4 with M4 Max

Compared contents in pHash-0.9.6.tar.gz before and after. Only config.guess is reverted. Unused index.html?p=config.git was included previously as well.

% diff -qr pHash-0.9.6 pHash-0.9.6-before
Files pHash-0.9.6/config.guess and pHash-0.9.6-before/config.guess differ
Only in pHash-0.9.6-before: index.html?p=config.git

sqlite3 in homebrew is "keg-only" formula meaning you can't find sliqte3ext.h at /opt/homebrew/include. Instead it only exists at /opt/homebrew/opt/sqlite/include.
