BATS tests: more resilient remove_same_dev_warning

Some CI tests are flaking in the SELinux test, possibly because
there's a new variation of the "multiple devices" warning I hadn't
seen before:

   WARNING: Creating device "/dev/null" with same type, major and minor as existing "/dev/foodevdir/null".

Solution: in remove_same_dev_warning(), remove "multiple" from
the match string.

Also: fix a Go test that wasn't cleaning up after itself. And
add an actual test to it, not just check-exit-status.
