www/p5-Gantry: correctly escape $

Summary

www/p5-Gantry: correctly escape $

In make(1), "$$" is the escaped version of "$", rather than the expected "\$". this expression was getting passed through to ${REINPLACE_CMD} as "s,\NV{..." rathern than the expected "s,$ENV{..." -- bug #229925 makes \N an illegal expression, as ordinary characters will be disallowed from being escaped in preparation for future changes to grant some of these escape sequences GNU-extended behavior.
