Be consistent with official docs in systemd service file

[kgizdov]

Service file kbfs.service uses the keyword mountdir to get configured mount point from user configuration and mount keybase FS. However, the official documentation say that users should set the entry for keyword mountpoint instead. Thus users are left with bad configuration until they manually dig this up and fix it themselves.

Pretty sure it is the docs which are wrong, e.g.

https://github.com/keybase/client/blob/v1.0.46/packaging/linux/run_keybase#L13

Like I thought: https://github.com/keybase/client/blob/607fc79192221b8eb1a9e770f609f5dacd2d5b9d/go/libkb/config.go#L798-L800

@kgizdov which "official documentation" are you referring to? https://keybase.io/docs/kbfs/understanding_kbfs correctly says mountdir.

No idea but FWIW this came together with a bugreport to Arch which claims the service file is also somehow wrong because fusermount is reporting no mountpoint in /etc/mtab (works for me, pretty sure fusermount is not broken, guessing this is just the case where ExecStartPre is permitted to fail because nothing needed to be unmounted).

@strib I swear that page said mountpoint when I looked at it before Easter. I guess this doesn't apply anymore.
