Bug 1393788 - Compress all JSDcov artifacts (.json files) into zip files after all tests are completed. r=gmierz,jmaher.

Building with "Linux x64 JSDCov", each suite of tests will produce a list of JSDCov artifacts (.json). This patch compresses all JSDCov artifacts into 1 zip file for each suite upon tests completion.
