Convert most of tools/dexfuzz/ to .bp

Had to leave the .PHONY target as that depends on a build variable
that is populated in other .mk files.

The dexfuzz script prebuilt target had to be renamed to dexfuzz-script
as it conflicted with the previous dexfuzz.jar target. That does not
change the name of the script that is copied into the bin directory

The instructions in the tools/dexfuzz/README did not seem to be
affected by this change.
