These may change over time and, as a matter of fact, have recently changed
in OVS master branch with commit fcdf8ae4a350 ("lib: Print nw_frag in flow
key.").

Instead, strip the flow key from the output.  To achieve that, the calls
to ovn-trace had to go through a bit of refactoring too.

OVN has weekly CI jobs that run against OVS master branch.  These were
failing due to the flow key dump changes:
