LU-10824 llite: don't use ll_mnt to get fstype name

Originally lustre would report using the fstype proc file either
'lustre' or 'llite'. This required us to query struct super_block
but its been a very long time since that is the case. This also
removes a direct use of ll_mnt. The fix is simply report 'lustre'.

Test-Parameters: trivial
