sys_sgetmask/sys_ssetmask: add CONFIG_SGETMASK_SYSCALL

Browse Source 
sys_sgetmask and sys_ssetmask are obsolete system calls no longer
supported in libc.

This patch replaces architecture related __ARCH_WANT_SYS_SGETMAX by expert
mode configuration.That option is enabled by default for those
architectures.
