Bug#952883: [live-build] binarie_onie lacks newline before errors

[jnqnfe@gmail.com]

Package: live-build
Version: 1:20191221
Owner: jnqnfe@gmail.com
Severity: minor

binary_onie takes the unusual (with respect to all other scripts) step
of outputting a series of dots as it progresses through various parts
of its script. these dots are all printed on the same line and finally
are terminated with 'done'. the problem is that if an error occurs, the
error should no doubt be placed upon a new line but is not.

patch to be submitted via salsa shortly (will amend commit with bug
number first)
