This patch introduces two signal tests, and generic test wrappers similar
to selftests/arm64/signal directory, along with the mangling testcases
found therein. arm_cpsr, dumped by the kernel to user space in the ucontext
structure to the signal handler, is mangled with. The kernel must spot this
illegal attempt and the testcases are expected to terminate via SEGV.
