fix missing abrt dependency python-argparse
---
#
# i use this way to detect and report (as changed state) when its missing when running in --check mode
#
# it installs this package only when its the only package to install
# so i'm workarounding the problem of yum, could not install only one package

use interpreter like python based on script path

script has the same shebang in all cases. it depends on the path to the script which interpreter is used

no special environment setup, not additional wrappers, without changing shebang in scripts

just one configuration file/directory to specify which tool should use which environment. compatible with SCL, virtualenv and other available ways to get different version in one system
