Bug#84734: apt: improve "could not lock" message

[Julian Gilbey <J.D.Gilbey@qmw.ac.uk>]

Package: apt
Version: 0.3.19
Severity: wishlist

The error message:
E: Unable to lock the administration directory, are you root?
might only make sense when the errno is Permission denied.  It might
make sense to say "Is another apt or dpkg running?" if the lock can't
be captured.
