perf test uprobe_from_different_cu: Skip if there is no gcc

Browse source 
Without gcc, the test will fail.

On cleanup, ignore probe removal errors. Otherwise, in case of an error
adding the probe, the temporary directory is not removed.

Fixes: 56cbeacf14 ("perf probe: Add test for regression introduced by switch to die_get_decl_file()")
