new 3d37b1794ce syscall: Add issetugid()
3d37b1794ce is described below
commit 3d37b1794ce6025aba454fcfc914a4f2428a3248

syscall: Add issetugid()
With CONFIG_SCHED_USER_IDENTITY the kernel has issetugid()
(sched/group/group_issetugid.c) and the user libc leaves out its stub, but
there is no system call. In a protected or a kernel build, a program that
calls issetugid() or secure_getenv() does not link: undefined reference to
issetugid.
Add the system call, next to the other calls of the user identity.
