[LTP] [PATCH 1/3] getrlimit/getrlimit03: fix breakage with Aarch32

[Steve Muckle <smuckle@google.com>]

A 64-bit ARM kernel running an Aarch32 user binary has the ugetrlimit
and prlimit64 syscalls, but not the getrlimit syscall. This test
currently assumes getrlimit is always available.

Modify the test so that it does not fail in this configuration.
