Enhance BUGS script.

Since RHBZ was updated, the old python-bugzilla program broke.  When
it was fixed, I found the (undocumented) ordering of the results from
the old tool was no longer true.

This commit adds a small Perl script to sort the output predictably.
Now bugs are sorted by both bug state and bug number, so the output
should be more stable than before.

Re-enable creation of the BUGS file in 'make dist'
(this reverts commit 91f3456244e7843768da659e24ce0aeeb4ebe4b0).

Also the BUGS file has been updated.
