perf test uprobe_from_different_cu: Skip if there is no gcc
[ Upstream commit 98ce8e4a9dcfb448b30a2d7a16190f4a00382377 ]
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: 56cbeacf14353057 ("perf probe: Add test for regression introduced by switch to die_get_decl_file()")
