init: Make chromeos-cleanup-logs skip symlinks.

Make the chromeos-cleanup-logs script only delete regular
files when cleaning up directories.

I think that this solves the longstanding puzzle of why
powerd logs are sometimes missing from feedback reports: the
powerd.LATEST and powerd.PREVIOUS symlinks are only created
at boot, so if the directory gets big and the system has
been running for a while, the symlinks can get deleted.

BUG=chromium:743125
TEST=manual: verified that the current chromeos-cleanup-logs
     deletes powerd.LATEST after i run e.g.
     "touch -m -d 'last sunday' -h powerd.LATEST" to give it
     an old mtime, but leaves it alone after making this
     change
