Log Message:
Remove stray extra distinfo file; this package uses the distinfo file
in ../libpreludedb via its Makefile.common. The extra one appears to
have been accidentally created while adding new distinfo hash
functions a couple years back.

This came to light because a new patch over the weekend didn't get
into this copy, and it seems that if a distinfo file appears in the
current directory, pkglint ignores the setting of ${DISTINFO_FILE}
even if it points somewhere else. Which is probably a bug.
