signal: move the "sig < SIGRTMIN" check into siginmask(sig)
All the users of siginmask() must ensure that sig < SIGRTMIN. sig_fatal()
doesn't and this is wrong:
UBSAN: Undefined behaviour in kernel/signal.c:911:6
shift exponent 32 is too large for 32-bit type 'long unsigned int'
the patch doesn't add the neccesary check to sig_fatal(), it moves the
check into siginmask() and updates other callers.
