system-config-run: bump base timeout to 3600

Many of our tests are actually running with a timeout of 3600; I think
between a combination of bumping timeouts for failures and
copy-pasting jobs.

We are seeing frequent timeouts of other jobs without this,
particularly on OVH GRA1.  Let's bump the base timeout to 3600 to
account for this.  The only job that overrides this now is gitea,
which runs for 4800 due to it's long import process.
