BUG: splunktaucclib detection fails when ucc-gen is run

[yaleman]

Description

It's running python3 -m pip show --version splunktaucclib and throwing exit code 1, probably because running it that way has nothing to do with the place it's installing the packages. (which is ./output/app/lib). This'd be another place it'd be good to see better error messages as the exit code 1 could mean a variety of things. (similar to #1600)

Using pip to check the installation status is an inherently flawed way of doing it in this context either way, as the environment with ucc-gen doesn't necessarily have the packages that are going to be installed into the app.

ERROR: This add-on has an UI, so the splunktaucclib is required but not found in package/lib/requirements.txt. Please add it there and make sure it is at least version 6.6.0.

Hi @yaleman are you able to share a repo where the issue is observed so I can try to reproduce it? What OS are you using to build an add-on?
