ctest_submit: Add HTTPHEADER option

Allow CTest script writers to specify additional HTTP headers to be sent
to CDash during submission.

The motivating case for this feature is a corresponding change in CDash.
This will allow projects to refuse submissions from any site not bearing
a valid authentication token.
