pfPorts: Minor php52 subport sync / typo correction

Small sync with FreeBSD ports only regarding
- Header (since switch to SVN)
- Copy-paste error (space vs. tab)

This is in hope to make smaller chunks for updating/syncing
the php52 and have smaller commits and make things more obvious
instead of large chunks.
Merge pull request #90 from matsimon/releng/2.0/php52-sync
