TST: Fix xfail for git component of `pd.show_version` tests on 32 bit builds

[mroeschke]

Two tests were xfailed in this PR that suddenly failed. #46842

[jbrockmendel]

spitballing: i wonder if we can record when xfail(strict=False) tests xpass to try to track down patterns in the relevant conditions

[mroeschke]

Yeah possibly we could have an automation flow that reads the test-data.xml and when there are xpasses in the logs we can write to an issue

These tests are also failing on pandas-wheels nightly linux builds https://dev.azure.com/pandas-dev/pandas-wheels/_build?definitionId=3&_a=summary

[simonjayhawkins]

skipped on pandas-wheels for now MacPython/pandas-wheels#182 so that nightly builds for Linux are uploaded to https://anaconda.org/scipy-wheels-nightly/pandas/files

[lithomas1]

Marking as blocker for release. The wheel filenames will be messed up if this is not fixed(this may prevent pypi uploads).

Thanks @lithomas1 the nightlies did upload but the the wrong prefix pandas-0+unknown- instead of pandas-1.5.0.dev0+849.g3bf2cb1b22- so were probably of no use. (we may need to delete these from the server)
