paygen: make keyset filter a bit more flexible

Support using the full keyset name in the signed image names and not
just the stripped down one.  This lets us sign the same image with
keysets from different boards and host them in the same dir.  Otherwise
the filenames are not unique.

TEST=`./` passes
