    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.
