fix: don't pass on arguments from node executable

When running a script that involves `ipfsd-ctl` and you pass on
additional parameters it used to pass on those parameters to
the subprocesses it spaws. This lead to issues especially with
`--inspect-brk` as it would spawn another inspector which then
would fail because there is already one running on the same port.

Fixes #202.
