TST: Increase tolerance on more arches

Not sure why this didn't hit Fedora when 3.10.0 was initially built, but
it is now during the F42 Mass Rebuild.

These tests are already covered by `arm64`-specific tolerances (aka
Apple Silicon), and while one or two won't need it, I've changed all of
these.

Additionally, instead of listing every single architecture, just
increase the tolerance on non-x86_64. Also, make a few tweaks to
existing conditions to make these all consistent.
