misc/cgo/testcarchive: permit SIGQUIT for TestSignalForwardingExternal
Occasionally the signal will be sent to a Go thread, which will cause
the program to exit with SIGQUIT rather than SIGSEGV.
Add TestSignalForwardingGo to test the case where the signal is
expected to be delivered to a Go thread.
Fixes #53907
