pkg/rpcserver: add unit tests, Manager mocks

Added more test coverage of the package and created an interface of
rpcserver to use it as the dependency (for syz-manager).

Also tried to cover with tests a private method handleConn(),
though it calls handleRunnerConn which has a separate logic in
Handshake(), which within handleConn() unit test we should've mocked.
This will require a refactoring of `runners map[int]*Runner` and
runner.go in general with a separate interface which we can mock as
well.

General idea is to have interfaces of Server (rpc), Runner etc. and mock a
compound logic like Handshake during a separate public (or private if it
has callable, if-else logic) method unit-testing.
