largefiles: use "ui.configlist()" to get largefiles.patterns configuration

current lfconvert implementation uses combination of "ui.config()" and
"str.split(' ')" to get largefiles.patterns configuration.

but it can not handle multiline configuration in hgrc files correctly.

lfconvert should use "ui.configlist()" instead of it, as same as
override_add does.

add another largefile to the new largefiles repo

round-trip: converting back to a normal (non-largefiles) repo with
"lfconvert --to-normal" should give the same as ../bigfile-repo

# Hmmm: the changeset ID for rev 5 is different from the original
# normal repo (../bigfile-repo), because the changelog filelist
# differs between the two incarnations of rev 5: this repo includes
# 'large' in the list, but ../bigfile-repo does not. Since rev 5
# removes 'large' relative to the first parent in both repos, it seems
# to me that lfconvert is doing a *better* job than
# "hg remove" + "hg merge" + "hg commit".
