Remove rmrf implementation from backend
This moves the code for removal of local database entries right into be_local.c, which was the last user of the rmrf() function we had in our utility source file. We can simplify the implementation and make it non-recursive as we know the structure of the local database entries. Signed-off-by: Dan McGee <dan@archlinux.org>
