Use upstream architecture names on Fedora 34+

https://fedoraproject.org/wiki/Changes/Python_Upstream_Architecture_Names

 - repalce patch 274 witch a sed call
 - update patch 353 to work both ways
 - add a new bcond to control the behavior: legacy_archnames

# This made sense at the time, see https://github.com/pypa/manylinux/issues/687#issuecomment-666362947
# However, with manylinux wheels popularity growth, this is now a problem.
# Wheels built on a Linux that doesn't do this were not compatible with ours and vice versa.
# We now have a compatibility layer to workaround a problem,
# but we also no longer use the legacy arch names in Fedora 34+.
# This bcond controls the behavior. The defaults should be good for anybody.
