nongnu: linux: Enable mt7921e driver.

Browse source 
In order to be able to use WiFi chip in P14s ThinkPad, the mt7921e module is
required.  This commit enables it in kernels that do have it.

I originally implemented this using a list of additional option, same way
%default-extra-linux-options is done.  However I quickly realized that
approach is not suitable for hardware enablement.  The older versions do not
support the same drivers as the newer ones.

Solution is to create a new procedure that generates the list for a specific
kernel version and use it as a default value for #:configs.

* nongnu/packages/linux.scm (nonguix-extra-linux-options): New procedure.
(corrupt-linux): Use it as default value for #:configs.
