tuna save <filename> allows you to save your kthreads tunables to
a file to be used by rtctl. There were several backslashes that produce
an error that pylint and Python (at least 3.12) gives a `SyntaxWarning:
invalid escape sequence`.
Convert the strings written to the file with raw strings to resolve the
warnings.
Tested by comparing the diffs of the files outputted by save.
