kselftest/arm64: Install signal handlers before output in FP stress tests

Browse Source 
To interface more robustly with other processes install the signal handers
in the floating point stress tests before we produce any output, this
means that a parent process can know that if it has seen any output from
the test then the test is ready to handle incoming signals.
