rc: scrub extensions.ini writing following a FreeBSD ports change

We don't have to do anything here anymore.  Since we started using
pkg(8) the extensions.ini was always consistent, but we needed to
make sure that the order is correct.  Some more cleverness was added
to no prevent other PHP modules from simply "plugging in", but since
they are not in one extensions.ini anymore it won't matter.

Expecting some splatter during upgrade, but hopefully also no more
php-suhosin clashes with php56-session not loaded.  :)
