transactions: change backupfiles format to use newlines

Previously the journal.backupfiles file was delimited by \0. Now we delimit it
using \n (same as the journal file). This allows us to change the number of
values in each line more easily, rather than relying on the count of \0's.

# Inspired by Subversion's XML log format.
