[ticket/11843] The twig lexer fixes DEFINE variables with underscores again

https://github.com/phpbb/phpbb3/pull/1708 accidentally stopped the twig lexer
from fixing DEFINE variables with underscores in them. This commit restores
that functionality.

[ticket/11843] Add checking DEFINE variables with underscores to template_test

To prevent the underscore in DEFINE variables from being forgotten again,
the template tests now test INCLUDEing a file based on the contents of a
DEFINE variable with underscores in it.
