Do not truncate return value of get{,e}[ug]id and setfs[ug]id syscalls

This should not be a user visible change unless the kernel does
something completely unexpected.  In the latter case, let user see
what is going on.

* uid.c (SYS_FUNC(getuid), SYS_FUNC(setfsuid)): Do not truncate
tcp->u_rval to uid_t on exiting syscall, return RVAL_DECODED.
