Add executable extension to debugger name, run dotest via binary

[scottmg]

Summary

Otherwise, when running the test suite on Windows:

• dotest.py will be opened in editor
• once running there'll be errors of the form ".../build/bin/lldb is not an executable"

(There are many other problems still, of course)

[scottmg]

Removed unrelated changes

I'm looking at this now.

This didn't break anything on Linux x86_64 cmake/ninja with ninja && ninja check-lldb.

MacOSX dosep.ty appears fine as well.

LGTM. Submitting momentarily.

Submitted.
