[OE-core] [PATCH V3 2/4] package_manager.py: use 'purge' instead of 'remove' in case of deb

[Chen Qi]

We need to use 'purge' instead of 'remove' for debian package backend when
removing packages at rootfs time. This is because that 'remove' command for
'dpkg' and 'apt-get' does not remove configuration files.
