Add dopackages.wrapper, a wrapper script around dopackages that sets up

build locking, log files, and cleans things up if a build fails.

This script is the primary starting point for a package build.  Symlinks
should be created in the form of dopackages.${branch} -> dopackages.wrapper
where ${branch} is currently one of 4, 4-exp, or 5.  This script takes the
place of the unofficial (i.e. uncommitted) dopackages.steveX scripts.
