Stopped a stalled install from costing a whole regression run (#641)

The Install softwares step runs apt-get update, an apt-get install and a pip
install, and it has stalled twice: 55 minutes on the SMP job of one run, and
more than two hours on the ThreadX job of the next, against a normal 27 to 152
seconds across every other run measured. In the second case the tests never
started at all.

No step in this template had a timeout, so a stall runs until the six hour job
limit. That turns a transient apt or PyPI problem into a lost run, and it hides
what happened: the job simply sits there, and the failure that eventually gets
reported says nothing about which step was stuck.

Bound the three steps that do real work. Ten minutes for the install, against a
normal worst case of 152 seconds. Fifteen for the build, which has run between 4
and 54 seconds. Sixty for the test step, which is the only one whose length
depends on the suites themselves; the longest observed is 37 minutes, and that
was with a wait in one test that has since been bounded.

A step that trips its timeout fails and names itself, which is the point. None
of these numbers is tight enough to trip on work that is merely slow.
