selftests/bpf: Fix xdpxceiver failures for no hugepages
xsk_configure_umem() needs hugepages to work in unaligned mode. So when hugepages are not configured, 'unaligned' tests should be skipped which is determined by the helper function hugepages_present(). This function erroneously returns true with MAP_NORESERVE flag even when no hugepages are configured. The removal of this flag fixes the issue. The test TEST_TYPE_UNALIGNED_INV_DESC also needs to be skipped when there are no hugepages. However, this was not skipped as there was no check for presence of hugepages and hence was failing. The check to skip the test has now been added.
