kselftest/arm64: signal: Skip tests if required features are missing
[ Upstream commit 0e3dbf765fe22060acbcb8eb8c4d256e655a1247 ]
During initialization of a signal testcase, features declared as required
are properly checked against the running system but no action is then taken
to effectively skip such a testcase.
Fix core signals test logic to abort initialization and report such a
testcase as skipped to the KSelfTest framework.
