[Buildroot] [git commit branch/next] purge-locales: further refactoring after removing man paths

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=805240bae841c221c1dc6d42b07fca31d595e298
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Since the man paths have been removed, it is no longer necessary to
grep them out and the loop can be simplified.
