Same fix than commit 826a9eb072 (tools: Fix regex syntax warnings with Python
3.12).
It clears out the warning:
```
$ xen/scripts/xen-analysis.py
xen/scripts/xen_analysis/cppcheck_analysis.py:94: SyntaxWarning: invalid escape
sequence '\*'
comment_line_starts = re.match('^[ \t]*/\*.*$', line)
```
The warning appears only the first time the command is run, then it disappears.
Fixes: 02b26c02c7 (xen/scripts: add cppcheck tool to the xen-analysis.py script)
