Makefile.proof: Add full paths and config to diagnostic output

GCC and GNATprove only print the file name in diagnostic messages, not
its full path. We'll replace the file name for all known files in the
configuration built for. For the `proof-allconfigs` target, we also
prefix the line with the current configuration (e.g. `linux::`).
