Upgrade the version of cpplint from 1.5.0 to 1.5.5.

Here, i've found a misleading cpplint errors generated by cpplint.sh in the progress of CI. And i've made sure that i've format the code by the Google code-style standard, with the necessary double-check by cpplint tool.

Finally, i've checked the releasing logs of cpplint, and found the following results:

So, could we upgrade the version of cpplint in the CI of kvrocks to 1.5.5 ?

I‘ve verified the upgrade was valid in my local repository CI checking progress.
