Fixes <https://issues.guix.gnu.org/44924>, in a cross-compilation context.
Having the source in inputs when computing search paths can break builds. One
example is a git checkout of the Linux source tree, where the source (a
directory) 'include' subdirectory gets picked up in C_INCLUDE_PATH and causes
conflicts with the includes provided by glibc.
* guix/build/gnu-build-system2.scm (set-paths): Remove any "source" native
input.
