scripts/php*.in: Explicitly define the path to sed.

The full path is detected by configure, resulting in a different build
depending on if it is built on a usrmerge or non-usrmerge system.

Since usrmerge systems contain compatibility symlinks for the
non-usrmerge paths, use the non-usrmerge path which is compatible in
both systems.
