Long stack traces from conda-build even in case of benign build failures

[h-vetinari]

After the switch to conda-build (in v4 of the ci setup), something that happens very regularly on feedstocks -- a failing build script -- will now (occasionally?) cause long error reports from conda, which make it more confusing where the error is coming from. Here's an example. Everything but the first and last two lines should not be there.

  ERROR: Failed building wheel for mesas
ERROR: Could not build wheels for mesas, which is required to install pyproject.toml-based projects

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install <package>

Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.

Example: CONDA_NO_PLUGINS=true conda install <package>


No report sent. To permanently opt-out, use

    $ conda config --set report_errors false

CC @jaimergp, who asked me to open this issue after it came up in discussion in last week's core call.

This was addressed by changing to conda-build instead of conda build. This conversation also started a series of changes in conda-build to report the exceptions in a less noisy way (e.g. conda/conda-build#5264).

I think we can close now :)
