post_gen_project.py hook fails on Linux

[mdpiper]

The post_gen_project.py hook fails on line 99

clean_folder(LIB_DIRECTORY, keep=keep)

on Linux. This issue doesn't occur on macOS.

To reproduce, use the plugin.yaml file from pymt_hydrotrend and call bmi-render:

bmi-render plugin.yaml .

If I comment out the problematic line in the hook, everything works fine.

This should be fixed with mcflugen/cookiecutter-bmi-wrap#10.
