Bug 1532893 - Retry packages tasks when doesn't r…

…espond. r=dustin

Bug 1486071 intended to fix this, but while the tasks are setup to
restart on exit status 100, there are multiple failure cases where doesn't respond and the exit status is not 100.

One is dget, when downloading package sources from
Eventually, those should move to fetch tasks, but in the meantime, we
bubble up get errors with an exit code 100.

mk-build-deps wraps a call to apt-get install, but doesn't return the
exit code that apt-get returns when apt-get returns one. It makes it
hard to distinguish the error modes, but mk-build-deps is unlikely to
fail on anything else than apt-get. Not all apt-get failures would be
due to availability, but that's a tradeoff we
decided was okay in bug 1486071.
