I don't see anything there that suggests it belongs in this
directory--quite the contrary:
run/ system information files describing various info
about system since it was booted
utmp database of current users; see utmp(5)
I interpret this to mean system-wide information, not information
about locked files (which could just as well be stored in
/var/spool/uucp/LCK).

On the other hand, it might make sense to consider whether we couldn't
use symlinks. People are bound to do their own porting rather than to
install a port, and the standard version would not find a lock made by
the ported version.
