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
Switch the strings written to the file with raw strings to resolve the
warning for this section of the code.
Tested by comparing the diffs of the files.

Changes in v2:
- Combine the second lines of '\n' to be concatenated with the
raw strings.
