Instructions for creating a new build environment using onu missing the -d flag

[pilonsi]

In the Testing section of the Basic illumos Workflow section, when it mentions using onu to create the new build environment the example command is missing the -d flag to point it to the locally built packages. Currently it is:

# onu -t new-nightly-be
#

When it should be:

# onu -t new-nightly-be -d /path/to/gate/packages/<arch>/nightly/
#

Missing the -d flag results in it trying to reach the ipkg.sfbay domain which no longer exists and it fails because it cannot resolve the hostname.
