binary_onie: fix lack of newline on error

this script outputs a series of progressive dots as progress is made,
finally terminated with ' done.'. however if an error occurs then the
error would end up being printed directly on the end of this instead of
on a new line since newlines are not printed after each dot. this fixes
this oversight.

Gbp-Dch: Short
Closes: #952883
