This patch adds grcov to linux64-ccov. Grcov is then used after code coverage collection to process the .gcno and .gcda files into a .info (LCOV-style) file. It also uses the 'linked-files-map.json' to rewrite symbolic links to the path that they point to. The .info file that is produced is called 'grcov_lcov_output_stdout' and is stored in the zip file 'code-coverage-grcov.zip'.
