[Unstable][PATCH 07/10] UBUNTU: [Packaging] rules: Remove undefined variables prev_{abinum, revisions}

[Juerg Haefliger]

Flagged by --warn-undefined-variables:
debian/rules.d/0-common-vars.mk:65: warning: undefined variable 'prev_revision'

The introduction of DEB_REVSION broke these variables and made them
undefined/empty. Luckily they serve no real purpose, so remove them.
