php: align Darwin and Linux versions again

Instead of pinning Darwin to older versions, add small patches to
configure.in (7.1) / configure.ac (7.2) to fix the build of the intl
extension on recent PHP versions on Darwin.

fix-paths-php7.patch also required changes -- since we now run autoconf
at build time (through ./buildconf), it needs to patch the input .m4
files instead of ./configure directly.
