Fix crash when old/new sigprocmask isn't safe to dereference. Bug #369360.

Since we want to use the set and oldset for bookkeeping we also want
to make sure they are addressable otherwise, like the kernel, we EFAULT.
Also use EINVAL instead of EMFILE as failure when sigset size is wrong.

Found by LTP testcases/kernel/syscalls/rt_sigprocmask/rt_sigprocmask02.
