[DTS][PATCH V1 2/2] framework/dts: fix result output by merging cases when parsing execution requirements.

[Ke Xu <ke1.xu@intel.com>]

In execution config, multi-run suites and cases are grammarly allowed.
 When we call for a suite multiple times, the new result will overwrite
 the old result totally.

This fix merges duplicated lines for suites when parsing the execution
 configuration, preventing the potential multiple run of suites and
 cases.
