[OE-core] [PATCH 3/4] testimage.bbclass: write testresult to json files

[Yeoh Ee Peng]

As part of the solution to replace Testopia to store testresult,
OEQA testimage need to output testresult into json files, where
these json testresult files will be stored into git repository
by the future test-case-management tools.

To configure multiple instances of bitbake to write json testresult
to a single testresult file, user will define the variable
"OEQA_JSON_RESULT_COMMON_DIR" with the common directory for writing
json testresult.
