jobs/repo-install-test: run a few hours later

Give OBS more time to build the repository, before verifying that we can
install all packages from the repository. Apparently, OBS publishes the
repository in WIP state, before all packages for a distribution have
been built.

This leads to problems in the "nightly" and "next" repositories. In
contrary to "latest", we do not bump soname versions when doing ABI
changes, so we require the user to have all installed Osmocom packages
built from the same timestamp. With recent changes in the OBS scripts,
we enforce this by having all packages built from the same timestamp
depend on the exact version of a dummy package with that timestamp as
version.

The repo-install-test installs all packages from the binary repository,
and so it fails, as it should, if the repository is in an inconsistent
state with some packages built today and some packages built yesterday.
