Due to "battery empty" on laptop I lost the Ubuntu 18.04 based
container, however...

> you can run the r_forestfrag_xy.py from ./raster/r.forestfrag which seems to be the one failing in 7.8 with Python 3.6.

we have a Centos VM with Python 3.6 which I used now.

- r_forestfrag_ncspm.py: OK
- r_forestfrag_xy.py: OK
- r_forestfrag_trivial.py: Failing, see below
