[PATCH v2 1/7] ia64: fix Python string escapes

[Benjamin Gray <bgray@xxxxxxxxxxxxx>]

Python 3.6 introduced a DeprecationWarning for invalid escape sequences.
This is upgraded to a SyntaxWarning in Python 3.12, and will eventually
be a syntax error.

Fix these now to get ahead of it before it's an error.
