allow_other cannot be disabled

[jbeich]

On FreeBSD using allow_other as regular user leads to EPERM.

$ mount_fusefs -o allow_other auto $(mktemp -d) /usr/bin/true
mount_fusefs: /dev/fuse on /tmp/tmp.JbO67Seu: Operation not permitted

but gitfs passes it by default (after annotating libfuse with printfs)

$ mkdir gitfs
$ gitfs https://github.com/PressLabs/gitfs/ gitfs
mount_fusefs -o nonempty,subtype=gitfs,allow_other,fsname=https://github.com/PressLabs/gitfs/ 5 /home/foo/gitfs
mount_fusefs: /dev/fuse on /home/foo/gitfs: Operation not permitted
fuse: failed to mount file system: No error: 0

In a similar vein,

$ gitfs -o allow_other <repo> <path>

doesn't actually alter default value for allow_other. Only the following does

$ gitfs -o allow_other=True <repo> <path>

which is unlike any other FUSE filesystem.

In my sysutils/fusefs-gitfs port flipping defaults fixes the issue for the following cases:

$ gitfs <repo> <path>
$ sudo gitfs <repo> <path>
$ sudo gitfs -o allow_other=true <repo> <path>
