ci: support coveralls

The patch adds an action that installs gcovr and a workflow that runs
regression test suites, produces a summary of current code coverage and
sends code coverage data to Coveralls. Coveralls is a web service that
lets you inspect every detail of your coverage. See Tarantool's LuaJIT
page on Coveralls [1].
