description:
Refactor and enable the signal3 ATF ptrace(2) test

Adapt the test to be independent from the software breakpoint trap
behavior, whether the Program Counter is moved or not. Just kill the
process after catching the expected signal, instead of pretending to resume
it.

This test passes.
