Bug#743462: mk-build-deps better failure mode

[Joey Hess]

Package: devscripts
Version: 2.14.1
Severity: normal

    system @root, 'dpkg', '--unpack', @deb_files;
    die("dpkg call failed\n") if ( ($?>>8) != 0 );
    system @root, shellwords($install_tool), '-f', 'install';
    die("install call failed\n") if ( ($?>>8) != 0 );

If apt-get - f install is unable to resolve the situation, it would be better
to run dpkg --remove on the temp package before exiting. This will leave
the system in its previous state on failure, rather than in some broken state.
