i18n: change output of largefiles for summary to distinguish from one for outgoing

Before this patch, largefiles extension uses "largefiles: No remote
repo" message not only for "outgoing" as status report, but also for
"summary" as summarized information.

This sharing prevents message translators from inserting white spaces
between "largefiles:" and "No remote repo" in translated message to
align column position of summarized information.

This patch changes output of largefiles for summary to distinguish
from one for outgoing.

This patch puts "no remote repo" into parentheses, because this is not
summarized information.
