bundle2: capture transaction rollback message output (issue4614)

The output from the transaction rollback was not included into the reply bundle.
It was eventually caught by the usual 'unbundle' output capture and sent to the
client but the result was out of order on the client side. We now capture the
output for the transaction release and transmit it the same way as all other
output.

We should probably rethink the whole output capture things but this would not be
appropriate for stable.

The is still multiple cases were output failed to be properly capture, they will
be fixed in later changesets.

Tests if hgweb can run without touching sys.stdin, as is required
by the WSGI standard and strictly implemented by mod_wsgi.
