Fix Coverage

[Lynskylate]

fix #33
Our coverage generation relies on the directory external/hessian2-codec/bazel/coverage/collect_cc_coverage.sh where collect_cc_coverage.sh is located. After updating the bazel version, I found the directory external/hessian2-codec/bazel/coverage/collect_cc_coverage.sh not exists, the hessian2-codec self is not in the external directory.

Just a workaround, I directly used the collect_cc_coverage.sh script in the bazel-tool directory.
It appears that Bazel's support for gcov is still experimental in nature; we can address this issue more effectively once its API stabilizes.

@zyfjeff It seems we haven't made any special changes to collect_cc_coverage.sh. What impact would using the bazel-tool's collect_cc_coverage have?

I can't remember why we should maintain this script separately, but relying directly on Bazel's script instead of our own should be the right direction

I haven't conducted an in-depth test, but it seems that the prof data generated by the version of collect_cc_coverage we forked at present is empty.
You also can change the .bazelrc CC_CODE_COVERAGE_SCRIPT to CC_CODE_COVERAGE_SCRIPT=bazel/coverage/collect_cc_coverage.sh for testing
