signal.h: use an explicit cast to silent compiler warnings

This patches include/linux/signal.h
There is an implicit cast from an integer to an
unsigned long (sigset_t) which causes compilers to generate warnings.
Different compilers could possibly produce different code.
This change has been tested over several years of use and is stable.
