Convert most of tools/dexfuzz/Android.mk 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
though.

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