Quote from `man NetworkManager.conf`:
When the default wired connection is deleted or saved to a new
persistent connection by a plugin, the device is added to a list in the
file /run/NetworkManager/no-auto-default.state to prevent creating
the default connection for that device again.
"/run" is obviously wrong. Fix it.

We need to copy all introspection files to the same directory when
building the documentation.
Note that we only require Meson 0.44, but for the documentation at
least 0.46 is needed because of a new functionality of
gnome.gdbus_codegen(). In this way we can still build on Travis CI
(without documentation).
