[Distutils] Interrogate distribution for an entry point command path

It's not, because I'm deliberately specifying that it shouldn't be, at
install time. This is an executable that is private to the application
and not for general availability on the host.

I'm modifying an existing application that invokes the program as a
subprocess, so I'm wanting to find that program as an external command.

Existing code assumes it is an external command on the shell PATH, but
I'm changing that so that it's not on PATH. I need to make a minimal
change and want to ensure that I get the right filesystem path based on
what the distribution knows about itself.
