Https-everywhere: Update install-dev-dependencies.sh to work with Debian Buster

[Jochen-A-Fuerbacher]

The script install-dev-dependencies.sh doesn't work with Debian Buster at the moment. The error is:

E: Unable to locate package python3.6-dev
E: Couldn't find any package by glob 'python3.6-dev'
E: Couldn't find any package by regex 'python3.6-dev'
E: Package 'chromedriver' has no installation candidate

In Debian Buster there are no python3.6-dev and chromedriver packages available. However, there are python3.7-dev and chromium-driver packages available.

The installation script should be updated so that installs the requiered dependencies also on Debian Buster.

After I run a release going to work on just setting these dependencies to Python 3 support. This is snowballing into issues every where. Thank you for your patience and submitting this issue.
