Dockerfile-for-pyinstaller

# Dockerfile to build single self-contained executable for smaht-submitr using pyinstaller.
# Tested with IMAGE values: centos, arm64v8/centos - for x86_64 and arm64 architectures respectively.
# FYI: It turns out that binaries built on RedHat (CentOS) work on Debian (Ubuntu); but not vice versa.
