Kernel: Replace usages of SIGSTKFLT with SIGSEGV
SIGSTKFLT is a signal that signifies a stack fault in a x87 coprocessor,
this signal is not POSIX and also unused by Linux and the BSDs, so let's
use SIGSEGV so programs that setup signal handlers for the common
signals could still handle them in serenity.
