Skip old branches for FIPS builders

This should fix the ineffective change made in
#558
(9f84063)

The `tags` in master.cfg are *factory* tags, not *worker* tags.
Skip old branches using `not_branches` instead.

Note that these are unstable and failing, except “Only Blake2” which
is stable, and only fails on 3.11.
(The 3.9 3.10 builders are stable and passing, but not very interesting
at this point.)
