fuse: add mtab entry asynchronously

Browse Source 
Instead of taking libfuse's approach to the bug referred
-- making use of an ad-hoc mount option --, we get over
the issue by not waiting for mtab manipulation to complete.
If mtab manipulation happens to fail for some reason, just
log an error message (instead of aborting the mount).
