Move configuration files to /etc/xpra

The default-settings.txt file is a configuration file
editable by user, so its place on Unix systems is
in /etc.

With this commit, configuration file with names defined in
'configuration_files' dict are not minified or compressed.

They are moved to '/etc/xpra' directory if DEB or RPM package
is built.

Test:

  1. Spawn container with Debian:

     podman run --rm -it -v $PWD:/work:rw \
         docker.io/amd64/debian:sid /bin/bash

  2. Inside container:

     export DEBIAN_FRONTEND=noninteractive && \
     apt-get update && \
     apt-get full-upgrade -yq && \
     apt-get install -yq git python3-setuptools && \
     cp -a /work /build &&
     find /build -type d -exec chmod 0755 '{}' \; && \
     cd /build && \
     git checkout '*' && \
         git clean -fdx && \
         rm -rf /tmp/xpra-html5 && \
         rm -rf /etc/xpra /usr/share/xpra/www && \
         rm -rf /root/rpmbuild && \
     python3 setup.py sdist && \
         python3 setup.py install /tmp/xpra-html5 && \
         python3 setup.py install && \
         python3 setup.py deb && \
     echo "Contents of dist tars:" && \
     tar tvf dist/*.tar.gz && \
     echo "Contents of /tmp/xpra-html5:" && \
     ls -la /tmp/xpra-html5 && \
     echo "Contents of /etc/xpra/html5-client /usr/share/xpra/www:" && \
     ls -la /etc/xpra/html5-client /usr/share/xpra/www && \
     echo "Contents of Debian packages:" && \
     find dist/ -name "*.deb" -exec dpkg -c '{}' \; && \
     echo "OK" || echo "FAIL"
