More syscalls.master cleanup:
sys_osigaltstack() is 7 years old and no longer needed; all glory to
the sys_sigaltstack()!
sys_ogetdirentries() is about 9 months old, but still acceptable
within our release cycle; move from STD to COMPAT_48 to make this
clearer for tedu@ next year.
sys_sbrk() and sys_sstk() are completely obsolete: all they do is
return ENOSYS.
ok guenther@
