t_setrlimit: Adjust resource limit to 20M

With ASLR enabled by default, RLIMIT_STACK test fails due to the fact
that default stack gap can be as big as 15M. Because of that the
resource limit of 4M

t_setrlimit: Adjust resource limit to 20M

With ASLR enabled by default, RLIMIT_STACK test fails due to the fact
that default stack gap can be as big as 15M. Because of that the
resource limit of 4M results in test program receiving SIGSEGV
immediately after exiting the setrlimit syscall. Since the idea of this
test is to check if rlim_cur does not extend past rlim_max, adjusting
the resource limit to 20M should not invalidate the test results.

Fix setrlimit_test:setrlimit_memlock when the system has exceeded vm.max_wired.

This uses the same fix as r294894 did for the mlock test. The code from
that commit is moved into a common object file which PROGS supports
building first.

Fix a typo (__FreeBSD__ -> __NetBSD__ when omitting setrlimit_nthr)

- Omit setrlimit_nthr testcase on FreeBSD (requires lwp.h, et al)
- Expect overflow with rlim_max at INT64_MAX, not UINT64_MAX (rlim_t is int64_t
on FreeBSD)
