[LTP] [PATCH V3] getrlimit03: adjust a bit of code to compatiable with mips32

[Hongzhi.Song]

Error info:
getrlimit03.c:104: FAIL: __NR_prlimit64(0) had rlim_cur =
ffffffffffffffff but __NR_getrlimit(0) had rlim_cur = 7fffffff

According to kernel code: [arch/mips/include/uapi/asm/resource.h]
RLIM_INFINITY is set to 0x7fffffffUL instead of ULONG_MAX on mips32.

 /*
 * SuS says limits have to be unsigned.
 * Which makes a ton more sense anyway,
 * but we keep the old value on MIPS32,
 * for compatibility:
 */
 #ifndef __mips64
 # define RLIM_INFINITY      0x7fffffffUL
 #endif

Adding conditional statement about mips to fix this.
