Update 'build-php.sh' script to build without extensions (#221).

Add new 'build-php-with-ext.sh' script that builds PHP with
mysqli and pgsql extensions support. Note that pgsql extension
has a dependency 'libpq5' that has to be installed on end user
machine.

Shipping both 'php-cgi' and 'php-cgi-mysqli-pgsql' PHP binaries
with PHP Desktop releases.
