FILEFLAGSMASK  sets the flags that are valid, not the flags that are
actually set - FILEFLAGS would do that.
So what we are actually doing is telling it all flags are valid, and
none are set (since FILEFLAGS is not set at all).

As far as I can tell, not specifying FILEFLAGSMASK is identical to
specifying it with VS_FFI_FILEFLAGSMASK, so either applying or not
should yield identical information in the binaries.
