ci: Let rootfs builds run for 2 hours (!)

We now have to do five builds of dEQP: one each for tools, GL, GLES,
Vulkan (release branch), and Vulkan (main).

dEQP is not a quick build, with even the tools build taking ten minutes,
at least three of which go to just pulling the SPIRV-Tools source.

Building all five takes a cumulative 60 minutes (10 tools, 11 GL, 9
GLES, 15 VK release, 13 VK main). That doesn't give us a load of time to
build everything else we need.

Two hours is obviously a completely unreasonable amount of time to spend
doing builds, especially for jobs which shouldn't really exist. But the
yak shave to allow the container jobs to be able to run on non-b2c
hardware has been a long one, and with no big-bang solution turning up
any time soon, we need to be able to actually do rootfs builds.

So, let's do the worst possible thing and go for a gigantic timeout.
