sys-apps/mlocate: Revbump - cleanup temporary files at cron.daily job

During updating database mlocate creates tmp-file. If daily cron job has failed
(for example, after reboot), tmp-files are left in disk.

Added rm command before updatedb to delete these orphained files.

Package-Manager: portage-2.3.0
Closes: https://github.com/gentoo/gentoo/pull/3096
