[tools] Fix python DeprecationWarning: invalid escape sequence

The python documentation says "it’s highly recommended that you use raw strings for all but the simplest expressions." (https://docs.python.org/3/library/re.html)

So do that with the attached patch generated by

    sed -i -e "s/re.search('/re.search(r'/g" $(git grep -l 're.search(')

The warning can be seen in e.g. python3.7:

    $ python3.7 -Wd
    >>> import re; re.search('\s', '')
    <stdin>:1: DeprecationWarning: invalid escape sequence \s
