libs,tools/include: Clean "clean" targets

There is no need for an extra "cleanlocal" target, we can use
double-colon rules instead.

Generated headers are now in tools/include/, so remove those file
there.

Remove -f flag as it's already in $(RM).

libs.mk:
  - don't try to remove "*.rpm" anymore.

libs/light:
  - "_paths.*.tmp" isn't created anymore.
  - clean "libxenlight_test.so" and "libxl_test_*.opic".

libs/stat:
  - don't remove $(DEPS_RM) from here as it is already done in
    "libs.mk".

libs/util:
  - fix clean of version-script file.

include/xen-foreign:
  - remove __pycache__
