python-packages: Remove __PYVENV_LAUNCHER__ environment variable 
Setting __PYVENV_LAUNCHER__ for Python package builds was added in
a91a992abb, but neither the commit message
nor the pull request[1] explain its purpose in detail.

My guess is this was done to set the shebang for installed Python
scripts. We now have a Makefile recipe to set the shebang, so it would
be unnecessary to set this variable for this purpose.

It appears that Python 3.11 has changed the handling of this (internal)
environment variable, and setting it appears to be causing build errors
for all Python packages.

This removes setting __PYVENV_LAUNCHER__ for Python package builds.
