[packages] php5: upgrade to 5.4.5

- php.ini: remove obsolete options
- drop patch 'patches/900-prevent_buildconf_force.patch' as php now supports
  newer autoconf versions 'buildconf --force' can be called after patching the
  source tree to update build system
- cross compiling issue regarding libdl still present, so because of the last
  point the corresponding patch has to be against configure.in but configure
- update timezone patches
