Tweaked/fixed a number of small runner things after a bit of use

- Added support for negative numbers in the leb16 encoding with an
  optional 'w' prefix.

- Changed prettyasserts.py rule to .a.c => .c, allowing other .a.c files
  in the future.

- Updated .gitignore with missing generated files (tags, .csv).

- Removed suite-namespacing of test symbols, these are no longer needed.

- Changed test define overrides to have higher priority than explicit
  defines encoded in test ids. So:

    ./runners/bench_runner bench_dir_open:0f1g12gg2b8c8dgg4e0 -DREAD_SIZE=16

  Behaves as expected.

  Otherwise it's not easy to experiment with known failing test cases.

- Fixed issue where the -b flag ignored explicit test/bench ids.
