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.
