obs: DEBTRANSFORM-RELEASE everywhere

[jnweiger]

All our packages should take care of auto incrementing their build release number for DEB builds the same way as they do for RPM builds.

Currenlty we use /usr/lib/obs/service/source_validator to issue an error when a commit does not change the version-buildrelease combination. (Dangerous for debian packages, as they cause repository checksum errors then -- no timestamps used there).

A *.dsc file containing

# https://github.com/openSUSE/obs-build/pull/147
DEBTRANSFORM-RELEASE: 1

auto-increments the build release number in classic rpm <CI_CNT>.<B_CNT> style.

Many packages already have that, but not all.

@kawohl Please help checking where it is missing.

The DEBTRANSFORM-RELEASE feature keeps counting, when the version number is incremented.
It should reset itself to 1.1 when the version number changes.
