Adrian Chiris f9a750fcaf Prevent providing privsep-helper paths outside /etc
This commit aligns privsep filters with other projects
e.g nova[1], cinder[2] to prevent a malicious user from
invoking privsep-helper with an arbitrary configuration file
in case it took control over an unprivileged neutron process.

To generate the sample neutron configuration files, run the following
command from the top level of the neutron directory:

tox -e genconfig

If a 'tox' environment is unavailable, then you can run the following script
instead to generate the configuration files:

./tools/generate_config_file_samples.sh
