[Buildroot] [PATCH 1/2] Makefile: add chmod before rm when cleaning.

Some build systems (looking at you golang) create read only directories
as caches.
As such rm -rf will actually fail, causing clean and <pkg>-dirclean to fail.
This patch will cause `make clean` to run chmod -R +w on the relevant
directory first, which will allow rm -rf to work.
This may be resolved if https://github.com/golang/go/issues/31481 is
resolved satisfactorily.
