Expose the pbulk logs outside of the sandbox

Add a new PBULK_LOG configuration variable that points to a directory
outside of the sandbox and that is used to record all pbulk build logs.
These logs are necessary to troubleshoot any build failures that happen
during the build, and are also useful under successful conditions to
get summaries about what was built.

Fixes #3.

 **STILL UNDER DEVELOPMENT; NOT RELEASED YET.**
 
+* Issue 3: Added a new `PBULK_LOG` setting to point at a location that
+  holds all build logs, and made the `build` command print out details
+  about such logs on success and failure.
+
 * Issue 4: Fixed the installable bootstrap kit generated during a build
   to not leak pkg_comp-internal paths.
