Makefile: Fix 'make distclean'
We forgot the '-r' option on the rm command to clean up the
Sphinx .doctrees working directory, which meant that
"make distclean" fails:
rm: cannot remove '.doctrees': Is a directory
Add the missing option.
Fixes: 5f71eac06e15b9a3fa1134d446f ("Makefile, configure: Support building rST documentation")
