ovs-bugtool: Ignore deprecation warnings.

Since we have to support many versions of Python, this commit
forces ovs-bugtool to ignore deprecation warnings.  They were
complaining about use of the md5 module whose replacement does not
appear until Python 2.5.  In Python 2.7 deprecation warnings are
ignored by default.

Bug #4373
