Redirect streams to /dev/null unless verbose enabled

Redirect stdout and stderr to /dev/null unless the verbose option
is specified. This is a usability enhancement for the majority
use case which is a daemon-like mode for logshifter in which no
output should ever be expected from the program. If the streams
are left open and undirected, readers may block waiting for
output from logshifter itself.

Show failure in jenkins log but success in STDOUT when jenkins build

Jenkins builds initially report success, but then fail during the
archiving step and report status as failure.  Jenkins client needs to
wait until the archive step is complete before checking the build
status.
