[ Upstream commit 3fde60afe1f84746c1177861bd27b3ebb00cb8f5 ]
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.
