fuse-bridge: Pass unknown option down to fuse
In Linux, certain "filesystem-specific" options (passed in string form in last
argument to mount(2)), such as "rootcontext" or "context" are in fact common to
all filesystems, including fuse. We should pass them down to the actual
mount(2) call untouched.
This is achieved by adding "fuse-mountopts" option to mount/fuse translator and
adjusting the mount helper to propagate it with unrecognized options as they
are encountered.
