[PATCH i-g-t v2 06/16] tests/kms_frontbuffer_tracking: remove TEST_MODE_ITER_BEGIN() from `fliptrack`

["Michał Grzelak" <michal.grzelak@intel.com>]

igt@kms_frontbuffer_tracking uses TEST_MODE_ITER_BEGIN(t) which consists
of nested for loops. However many loops can be omitted due to continue
statements. This obfuscates following the execution of any given
codepath. Replace TEST_MODE_ITER_BEGIN(t) for fliptrack tests with macro
definition and remove loops that are skipped.

v1->v2
- indent for-loops (Mohammed)
