Debugger can only attach to a process with executable `coda-libp2p_helper`.

Currently debugger checks the sub-process' executable against `coda-libp2p_helper` name to detect libp2p helper. This makes impossible to use debugger with Mina when the helper is named differently, or specified with the whole path (like in local build).

One of the ways how to handle this is to check the executable name in the user space.
