Liav A 5a649d0fd5 Kernel: Return EINVAL when specifying -1 for setuid and similar syscalls ...

For setreuid and setresuid syscalls, -1 means to set the current
uid/euid/gid/egid value, to be more convenient for programming.
However, for other syscalls where we pass only one argument, there's no
justification to specify -1.

This behavior is identical to how Linux handles the value -1, and is
influenced by the fact that the manual pages for the group of one
argument syscalls that handle ID operations is ambiguous about this
topic.
