syscalls/setrlimit: add setrlimit04

With early patches for stack guard gap, gap size was included in stack
size. This caused failures for new processes (E2BIG) when ulimit was
set to anything lower than size of gap.

  # ./setrlimit04
  tst_test.c:898: INFO: Timeout per run is 0h 05m 00s
  setrlimit04.c:53: BROK: execlp(/bin/true, /bin/true, ...) failed: E2BIG
  setrlimit04.c:61: FAIL: child process exited with 2

commit 1be7107fbe18 "mm: larger stack guard gap, between vmas" sets default
gap size to 1M (for systems with 4k pages), so let's set stack limit to 512kB
and confirm we can still run some trivial binary.
