temp/xkeyboard-config: enable Nokia N900 keyboard (MR 5613)

upstream erroneously dropped N900 configuration in xkeyboard-config 2.42. until
this is fixed upstream, fork the package. set it to build only for armv7 to
reduce any possible effect on other devices in pmos.

Closes: https://gitlab.com/postmarketOS/pmaports/-/issues/2923
