Remove PT_GET_SIGMASK / PT_SET_SIGMASK

These operations cloned Linux's specific PTRACE_GETSIGMASK / PTRACE_SETSIGMASK.
This feature was useful in applications like rr/criu/reptyr-like, where
the ptrace(2) interface is abused for the purpose of constructing an arbitrary
process. It's not reliable and not portable. For the NetBSD case it will be
better to invent something dedicated for serializing and deserializing a
process with threads.
