fix(i18n): remove Gentoo workaround that is no longer needed

Gentoo no longer sets KEYMAP to something like "-u pl2", instead
it is set to "pl12".

This piece of code is part of the very original commit of the i18n
dracut module from 2010 - 87122af

There is no mention of '-u' in the oldest version of the wiki from 2013
https://wiki.gentoo.org/index.php?title=Keyboard_layout_switching&diff=1320347&oldid=16937

Remove this workaround that is no longer used or tested to
make it easier to reason about the code.
