kerndat: Mark memfd_create(MFD_HUGETLB) unavailable when ENOSYS is returned
Some users on Raspberry Pi report that the kerndat checking for
memfd_create(MFD_HUGETLB) support returns ENOSYS even when memfd_create
syscall is available. We currently treat this error as unexpected and
return error. This commit marks the memfd_create(MFD_HUGETLB) as
unavailable when ENOSYS is returned.
