GH Actions (macOS): Fix filtering of experimental packages

[mkoeppe]

Filtering by $targets_pattern is broken, so the jobs for experimental packages do too much work.

see for example https://github.com/sagemath/sage/runs/4752780943?check_suite_focus=true, which was supposed to only build packages starting with 0-g, but TARGETS_OPTIONAL=scipoptsuite modular_decomposition awali gdb deformation cocoalib surf gambit libtheora lie gap3 valgrind qepcad.

We also update some tox.ini settings for macos.
