Fix return code for __libc_signal_* functions

The functions do not fail regardless of the argument value.  Also, for
Linux the return value is not correct on some platforms due the missing
usage of INTERNAL_SYSCALL_ERROR_P / INTERNAL_SYSCALL_ERRNO macros.

Checked on x86_64-linux-gnu, i686-linux-gnu, and sparc64-linux-gnu.
