Subject: gnu: cross-kernel-headers: Fix build.

This fixes a regression introduced in
0e2251fcf8189a4f642074d3aa898221b29c3a55, as "make headers_check" does not
actually build the headers in newer versions, instead "make headers_install"
built them as a side effect.

* gnu/packages/cross-base.scm (cross-kernel-headers)[arguments]: Adjust build
phase to call the correct Make target.  While at it, migrate to MODIFY-PHASES.
