  script: fix "Unescaped left brace in regex is deprecated" warnings.

checkpatch uses perl regex which do not escape curly braces.
In Perl 5.22 or higher, unescaped left curly braces in a regex are
deprecated and will outputted a warning. and this will be an error
rather than a warning in future versions (maybe 5.26?).
This change provides suppress above problem.
