Merge #11842: [build] Add missing stuff to clean-local

b341143 [build] Add missing stuff to clean-local - test/functional/test_framework/__pycache__ - test/cache (Karl-Johan Alm)

Pull request description:

  After doing
  ```
  ./autogen.sh && ./configure && make
  make clean
  make distclean
  ```
  and moving `.gitignore` aside, the following files still remain after this patch:
  ```
  	Makefile.in
  	aclocal.m4
  	autom4te.cache/
  	build-aux/compile
  	build-aux/config.guess
  	build-aux/config.sub
  	build-aux/depcomp
  	build-aux/install-sh
  	build-aux/ltmain.sh
  	build-aux/m4/libtool.m4
  	build-aux/m4/ltoptions.m4
  	build-aux/m4/ltsugar.m4
  	build-aux/m4/ltversion.m4
  	build-aux/m4/lt~obsolete.m4
  	build-aux/missing
  	build-aux/test-driver
  	configure
  	doc/man/Makefile.in
  	src/Makefile.in
  	src/config/bitcoin-config.h.in
  ```

  Most are automake related so I guess it's fine if they litter around.
