Subject: Escape curly braces in def-check.pl regexes

Recent versions of Perl issue a warning or error when an unescaped
open curly brace is used in a position where it might introduce a
quantifier in a regular expression.  Escape all regexp literal curly
braces in def-check.pl.

(cherry picked from commit 523e4ab050b13404a6929cc56ef873de8023e25c)
