[bug#49025] [[PATCH v2 core-updates] 05/37] net-base: Fix cross-compilation, eliminating %build-inputs & friends

[Maxime Devos]

"source" is not in %build-inputs when cross-compiling, so another
approach for referring to the package source code is needed.

* gnu/packages/admin.scm (net-base)[arguments]<#:builder>: Eliminate
  %build-inputs and %outputs.
