build: use $(RM) in Makefile for consistency

Also allows someone to reassign `$RM`, e.g. with `RM=rm -v` instead of
`rm -f` (the default) should they want to. We're currently using a
mixture of `$(RM)` and `rm -f`.

There are a couple of places which aren't doing -f, have them do it for
consistency.
