[PATCH 1/2] filter.btrfs: new filter for property messages

[David Sterba <dsterba@suse.com>]

The error message in newer btrfs utilities contains name of the
property, we want to filter it out so it matches golden output. There's
an optional parameter with property name that is matched against the
command output.
