Determine dependencies of Windows resource files

Windows resource files support a subset of C preprocessor directives.
Among others they can have #include directives.

Use QMake's own scanner to retrieve the files that are included by a
Windows resource file and add them to its dependencies.

For the test case the TestCompiler class had to be extended:
runCommand is now public, and commandOutput is less peculiar.

Fixes: QTBUG-3859
