build-system/gnu: Remove #:path-exclusions parameter.

* guix/build/gnu-build-system.scm (set-paths): Remove `path-exclusions'
  parameter.  Replace `relevant-input-directories' by
  `input-directories'.
* guix/build-system/gnu.scm (gnu-build): Remove `path-exclusions'
  parameter; don't pass it in BUILDER.
* guix/build-system/cmake.scm (cmake-build): Likewise.
