runtime: revert "skip TestLldbPython when lldb is too old"
This reverts commit
d2170040617231a26ab0722d093ecb19e2ba8302.
Reason for revert: It broke all the darwin builders; it's also not
obvious how the weird darwin versions (900, 1000) relate to the > 3.9
requisite, so I'm not sure how to decide about skipping in a robust
way. It's better to revert the check for now.
Fixes #28028
