As the definition of NSIG_BYTES is based on NSIG defined in <signal.h>,
NSIG_BYTES cannot be used in files that use kernel sigset_t.
Add another wrapper around print_sigset_addr_len_limit function that
takes one argument less than print_sigset_addr_len wrapper. This new
wrapper is going to be used in cases when the length argument is equal
to NSIG_BYTES.
