[libvirt] [PATCH] Use python discovered through env instead of hardcoding a path

[Matthias Bolte]

This is more flexible regarding the location of the python binary
but doesn't allow to pass the -u flag. The -i flag can be passed
from inside the script using the PYTHONINSPECT env variable.

This fixes a problem with the esx_vi_generator.py on FreeBSD.
