Add platform_specific_behavior tag to test targets that use mark (#21609

)

This PR adds the `platform_specific_behavior` tag to the `python_test`
targets of 4 additional test files in this repo.

These test files use this repo's custom
`pytest.mark.platform_specific_behavior` mark to indicate tests are
high-value to test on non-Linux-x86_64 platforms. However, they were not
being run in CI because the testing invocation uses both Pants-level tag
and Pytest-level mark filtering: `./pants
--tag=+platform_specific_behavior test :: -- -m
platform_specific_behavior`.

This PR fixes the current problems identified in #21608, but doesn't
stop us from making the same mistakes in future (and thus doesn't close
that ticket).
