Fix Python not being found for lttngpy in Windows debug mode

[christophebedard]

Closes #86

I found this fix in a few other packages that use Python in CMake.

Trying a packaging_windows_debug job first:

• packaging_windows_debug

Trying a packaging_windows_debug job first:

In general, we prefer not to use the packaging_* jobs for debugging. That's just so that they have a relatively "clean" history of what has happened nightly. Instead, we prefer to use https://ci.ros2.org/view/All/job/test_packaging_windows/ .

In this case, it has already been done, so you can just let it run. But just for future reference.

Seems reasonable to me, assuming CI comes back green.

Oh, sorry! I should've looked for a test_* equivalent.

Seems like lttngpy now builds successfully, so let's run full CI, including a Windows debug job:

• Linux
• Linux-aarch64
• Windows
• Windows debug

Just so you know; we have other, unrelated failures in Windows Debug CI at the moment. So I expect that job will fail, but it should get past the compilation phase and into running tests before doing so.

It ended up passing, probably because I only tested --packages-above lttngpy.
