wix: restore COPYING.rtf

This got truncated to 0 bytes in 0ab651b5f77c when the Phabricator extension
crashed because it's a binary file.  That caused the license page in the WIX
installer to be empty.  I don't remember if I needed to resubmit after the bug
was fixed, so let's try this again with the current stable.  If this fails, I'll
retry with 5.1 to see if this is a regression in the API changeover last cycle.
