Revert the gnupg/sequoia signing sub-packages, too much headache
Ship the Sequoia signing macros as a %doc you can easily just copy
to /etc/rpm to enable, this is much less hassle for what is more
of a tech-preview feature at this time.
Obsolete rpm-sign-gnupg and -sequoia in case somebody had these
installed on the stream, but these haven't been part of any official
(pre)release so we can drop them before GA.
