Allow using obexd without systemd in the user session

Not all sessions run systemd --user and in some cases one may be missing
systemd all together.

Provide the correct path instead of /bin/false, allowing dbus to start
the service in such cases.

DBUS implementations can ignore the Exec line all together when run in
systemd aware mode - at least the OG dbus does that. So ultimately this
change is a no-op for the systemd --user case.

On my system, this is literally the only non-system service which uses
/bin/false.
