fix(cargo-php): get_ext_dir()/get_php_ini(): stdout noise tolerance

[kakserpom]

cargo-php fails to detect extension directory if there's a startup error in PHP.

Error: Failed to create extension directory at "\nWarning: PHP Startup: Invalid library (maybe not a PHP library) \'libuntitled5.dylib\' in Unknown on line 0\n/opt/homebrew/lib/php/pecl/20240924-zts"

Caused by:
    No such file or directory (os error 2)

It's pretty annoying as it makes you go to php.ini and remove extension=... manually.
