args: allow_root default False

[milahu]

make compatible with default config in /etc/fuse.conf

allow_root=True requires user_allow_other, which is default off

error was

fusermount: option allow_other only allowed if 'user_allow_other' is set in /etc/fuse.conf

edit: dammit, still getting the error, even with -o allow_other=false,allow_root=false
edit 2: fixed by removing the args.allow_root = True code
