MAINT: rename universal2 manually

* until an upstream multibuild solution is ready,
"manually" rename `universal2` wheels to require
MacOS version `12.0` minimum in a manner similar
to what we are doing for the thin arm64 mac wheels

* based on the analysis of universal2 wheel names in logs:
#150 (comment)
and recent nightly uploads:
https://anaconda.org/scipy-wheels-nightly/scipy/files#
look like we want to move from `10_9` to `12_0` universal2
file names

* we should definitely check the logs to make sure this works,
probably by looking at what filename gets targeted by the pip
install command in the `Install wheel and test` stage
for `universal2` CI runs (the `mv` command is verbose and
should also print out the renamed file)
