locate(1): Bring in some updates/fixes from FreeBSD
* The default value of "FILESYSTEMS" option is now determined using lsvfs(1),
which contains all local file systems that are not synthetic, loopback mounts
or read-only.
* New config option "PRUNEDIRS" in /etc/locate.rc with default value of ".git"
to ignore the ".git" directories when making database.
* Warn when locate.updatedb(8) is directly run by root
* Some cleanups (no functional change)
* Improve license declarations, fix white spaces and typos
