Fix the signal code on 32-bit breakpoints on arm64
When debugging 32-bit programs a debugger may insert a instruction that
will raise the undefined instruction trap. The kernel handles these
by raising a SIGTRAP, however the code was incorrect.
Fix this by using the expected TRAP_BRKPT signal code.
