etc/dists/scripts/*: Get rid of 'echo -e' bashisms

Apparently using 'echo -e' is non-portable. In these scripts
this is harmless since they are to be run by bash (first line
specifically says #!/bin/bash). But since -e functionality
(i.e. interpretation of backslash sequences line \n and \t)
is not required here, just remove '-e' flag.
