mail-filter/opendkim: update sendmail/libmilter dependency.

As reported in bug 833778, it would be nice if we could bind to the
libmilter subslot with an := dependency. In the existing ebuild, that
wasn't possible because we accepted either libmilter || sendmail, and
using := within an any-of clause is disallowed.

Fortunately, the "|| sendmail" portion of that is a relic, for
versions of sendmail that don't themselves use libmilter. All versions
of mail-mta/sendmail in the tree today do, so we can drop the sendmail
portion of that any-of dependency entirely, and then afterwards add
the := to libmilter.

Closes: https://bugs.gentoo.org/833778
