`_list_tests()` runs the kernel to list tests, strips printk timestamp
lines via `extract_tap_lines()`, then drops the dummy TAP header from
the cleaned `lines`. However the subsequent regex filter mistakenly
operates on the original `output` instead of the cleaned `lines`. When
the kernel output includes timestamp prefixes (common with UML or slower
setups), e.g.:
[ 0.100000] suite.test1
[ 0.100000] suite.test2
the anchored regex `^[^\s.]+\.[^\s.]+$` rejects them and `--list_tests`
returns an empty list.
Filter `lines` instead of `output`, matching the behavior of the
adjacent `_list_tests_attr()` which already returns the cleaned list.
Add a regression test with timestamp-prefixed input to verify the fix.
