Jeremy Stanley 5283222dd5 Make install-distro-packages.sh more robust
Introduce a retry loop in install-distro-packages.sh which will
attempt index updates and package installation up to 3 times if the
bindep list is unsatisfied, so as to mitigate intermittent network
failures. Add a clear error message after the last try indicating
the list of packages which were not installed.
