Mario brought to my attention that the hugetlb_fault_after_madv test
is currently always skipped on s390x.

Let's adjust the test to be independent of the default hugetlb page size
and while at it, also improve the test output.

This series has been successfully tested. Now when executing the
hugetlb_fault_after_madv selftest the benefits of both patches could
be observed.
# ./hugetlb_fault_after_madv
TAP version 13
1..1
# [INFO] detected default hugetlb page size: 1024 KiB
ok 1 SIGBUS behavior
# Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0
