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.
