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
