description:
tests/lint2: fix regular expressions containing backslash

In regular expressions, a backslash must be doubled. In this case, ATF
didn't complain because the single backslashes were used in the pattern
'\($2\)', where they produced '\(...\\)'. Omitting the backslash for the
closing parenthesis was apparently OK; other regex implementations
complain about this.
