borg delete: only commit once, fixes #3823 

borg delete was slower than required when it deleted multiple archives
as it committed repo and cache once per archive.

borg prune (doing a similar job) is faster as it commits only once for
all deleted archives.

borg delete now also only commits once and also (similar to borg prune)
only outputs a overall statistics for all deleted archives.

log output of borg delete was made similar to borg prune.
