Engine enumerated test names have changed so fast-feedback.testlist needs
to be updated. However listing all engines there won't scale. So instead
add new tests cases which iterate all engines internally.

v2:
 * Fix basic-all test name.
 * Fix params to basic (bool false to zero).
 * Use I915_EXEC_DEFAULT in has_extended_busy_ioctl to workaround stateful
   contexts for now.
 * Have only basic-all in BAT. (Chris)

v3:
 * Don't overload I915_EXEC_DEFAULT. (Chris)
