build-system: cmake: Rework cross compilation.

Move the extra configure flags for cross building out from the build side code and instead
prepend them to the configure-flags.

Use new procedure cmake-system-name-for-target to add support for hurd and
bare-metal targets.

* guix/build/cmake-build-system.scm (configure): Move cross build flags from
here ...
* guix/build-system/cmake.scm (cmake-cross-build): ... to here.
(cmake-system-name-for-target): New procedure.
