    fuse: guestunmount: Make the -v (verbose) option do something useful.
    
    guestunmount had a -v / --verbose option, but it didn't change the
    behaviour of the program in any way.
    
    Make it print the invocations of the underlying fusermount program.
    
    (cherry picked from commit 6dee5a4152a1e8a1b82f18c1f393dfc4ec89739e)
