    ltp: Use a legal bad address for mips in setrlimit05.c
    
    This testcase fails on mips32. The process is killed by SIGBUS which
    is not as expect.
    
    This is because:
    ((void *)-1) is not a legal bad address which causes the process
    killed by SIGBUG on mips.
    
    'tst_get_bad_addr()' returns an address that should works on mips
    and other arches.
