llvmpipe: Use lp_build_round_arch on IBM Z (s390x)

Browse Source 
LLVM has all the required intrinsics available on IBM Z, so use them for
rounding operations (they will be implemented as a single instruction).
This change makes the test case lp_test_arit pass, because it avoids
using the buggy generic code.

v2: update .gitlab-ci/cross-xfail-s390x to reflect passing lp_test_arit
