fusermount: Check for argv[0] being present (#577)

It is perfectly legal to execute a program with argc == 0 and therefore
no argv.
fusermount needs to check for this case, otherwise it will pass a NULL
poiunter to strdup() and cause undefined behavior.
Especially since fusermount is setuid root, we need to extra be careful.
