🐛 Fix exec_args for execvp

[jmontleon]

I realize the goal is to get rid of this script, so no issue if we don't want to bother merging this. But the first arg for execvp is supposed to be the command itself.

Instead of

user         878     876  1 12:49 ?        00:00:15 java-external-provider --port 14651 --port=50094

It now shows:
