ltp: Use a legal bad address for mips in setrlimit05.c

Browse Source 
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.

(From OE-Core rev: e45948d4be14c14eff0a5c8c8597a7523f2edff1)

Subject: [PATCH] setrlimit05: Use another method to get bad address
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.
