[PATCH OSSTEST] ts-debian-install: increase time allowed for xen-create-image

[Ian Campbell <ian.campbell@citrix.com>]

This step is consistently timing out when run on cubietruck-*. Judging
from the logs it appears to be completing during the 30s slack added
by tcmdex (i.e. after the timeout message the rest of the output
appears in the test step log).

Looking at the results on arndale-* (which looks to pass reasonably
reliably) I see that the regular test-armhf-armhf-xl job takes around
550s to do the xen-create-image while test-armhf-armhf-xl-rtds
typically takes around 1100s (twice as long).

On cubietruck-braque test-armhf-armhf-xl uses 900s. One could
therefore extrapolate that test-armhf-armhf-xl-rtds might need more
than 1800s and not be too surprised that it appears to need something
a bit more than 2000s in practice. 2500s seems like sufficient
headroom.

For comparisson with arm on x86 godello takes around 210s in the
normal case and 680s with RTDS (>3x slower) while nocera takes 265s
and 640s (2.4x). (Those are from nearby but not identical flights in
order to match up the host).

Dario, Meng, I suppose a 2-3x slow down with RTDS on a dom0 operation
(with no domains running) such as xen-create-image is not unexpected?
