ID_INTEGRATION is not being updated with hwdb entries, asign the new
value to it when hwdb has been imported.
We still need the 65-integration.rule assignment for devices that aren't
in hwdb.
While at it remove unneeded check in 70-touchpad.rules, as it was not
added for 70-joystick.rules with the statement if ID_INPUT_* is set and
ID_INPUT not, there is a bug elsewhere. And remove unneeded gotos in
both files.
Follow-up for a4381cae8b.
Files in this directory contain configuration for systemd-udevd.service, a daemon that manages symlinks to device nodes, permissions of devices nodes, emits device events for userspace, and renames network interfaces. See man:udev(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of service itself. Use 'systemd-analyze cat-config udev/rules.d' to display the effective config.
