selftests: openvswitch: Fix escape chars in regexp.

Character sequences starting with `\` are interpreted by python as
escaped Unicode characters. However, they have other meaning in
regular expressions (e.g: "\d").

It seems Python >= 3.12 starts emitting a SyntaxWarning when these
escaped sequences are not recognized as valid Unicode characters.

An example of these warnings:

tools/testing/selftests/net/openvswitch/ovs-dpctl.py:505:
SyntaxWarning: invalid escape sequence '\d'

Fix all the warnings by flagging literals as raw strings.
