Handle the case that hugetlbfs is not supported. To make it easier
for debugging.

On a system that does not support hugetlbfs. There will be no such
HugePages_Free entry in /proc/meminfo. And consequently freepgs will
be empty. The huge pages availability check will fail and the test
will be started anyway:
  ./run_hugetlbfs_test.sh: line 47: [: -lt: unary operator expected
  ./run_hugetlbfs_test.sh: line 60: 12577 Aborted
      (core dumped) ./memfd_test hugetlbfs
  Aborted (core dumped)
