Fix decoding of get[ug]id, gete[ug]id and setfs[ug]id return values

* defs.h (SYSCALL_NEVER_FAILS): New syscall flag.
* linux/dummy.h: Change redirection for sys_get[ug]id, sys_gete[ug]id
and setfs[ug]id.
* linux/*/syscallent.h: Set SYSCALL_NEVER_FAILS flag for get[ug]id,
gete[ug]id and setfs[ug]id syscalls.
* process.c [LINUX] (sys_getuid, sys_setfsuid): New functions.
* syscall.c (NF): New shorthand macro for use in syscallent.h files.
(get_error): Check SYSCALL_NEVER_FAILS flag.
