Subject: [PATCH] fix(xcat-core): the Genesis deb version never advances past
 snap000000000000

Every Genesis deb the Ubuntu dep pipeline publishes is versioned
2.19.0-snap000000000000. apt never upgrades an installed
xcat-genesis-base, so the channel cannot ship a Genesis fix.

Release is a tracked placeholder that buildrpms.pl overwrites with the
commit time. The dep job clones xcat-core only to build the Genesis
debs, so buildrpms.pl never runs there and builddebs.pl reads the
placeholder as an authoritative release.

builddebs.pl now treats an all-zero Release as an unstamped tree and
falls back to the commit time. snap_release() renders a real time, so
no build ever writes that value.

builddebs_release_placeholder.t covers it. The test fails on the
unfixed tree with snap000000000000.
