selftests/vm/run_vmtests: adjust hugetlb size according to nr_cpus
Fix userfaultfd_hugetlb on hosts which have more than 64 cpus.
---------------------------
running userfaultfd_hugetlb
---------------------------
invalid MiB
Usage: <MiB> <bounces>
[FAIL]
Via userfaultfd.c we can know, hugetlb_size needs to meet hugetlb_size
>= nr_cpus * hugepage_size. hugepage_size is often 2M, so when host
cpus > 64, it requires more than 128M.
