Let extra-source-files mark a package as dirty (commercialhaskell#1891,

commercialhaskell#2040).

This is necessary for packages that use a custom Setup.hs
(`build-type: Custom`).  Previously, stack wouldn't rebuild the package
if the only changes were to the `extra-source-files`.

Stack was already marking the package as dirty if `data-files` changed;
this just hooks `extra-source-files` into the same mechanism.
