Fix hook-function:

- Thread stoppage is now complemented by sigaction to catch injected
  threads (sigaction is not used exclusively because the rest of the
  program could be trying to use sigaction itself in the meantime - this
  is a real thing, ask Dolphin)

- mprotect is no longer used due to max_protection possibly getting in
  the way; instead, a copy is created and mapped onto the original.
