Move get*id and getgroups definitions to syscalls.list (bug 14138).

Move get*id and getgroups definitions to syscalls.list (bug 14138).

Continuing the move of syscall definitions to syscalls.list, where the
removal of support for old kernel versions has made this possible,
this patch moves various definitions of get*id functions and
getgroups.  The previous C definitions were because of the transition
to 32-bit uids and gids.

Tested for x86.
