Log message:
Remove mk/find-prefix.mk usage from the misc category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Log message:
Add SHA512 digests for distfiles for misc category

Problems found locating distfiles:
	Package colorls: missing distfile ls.tar.gz
	Package molden: missing distfile molden-4.6/molden4.6.tar.gz
	Package softmaker-office-demo: missing distfile ofl06trial.tgz

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.
