Simplify JTAG automake input file:

- Consolidate all individual driver variables into DRIVERFILES.
  - Eliminates all empty 'else' conditional clauses.
- Move minidriver files to top of file.
- Use MINIDRIVER conditional to build only driver(s) that will be linked.
- Eliminate superfluous whitespace.
