[Module-build-general] Remove YAML document header from META.yml spec

[Michael G S. <sc...@po...>]

I just got a patch for MakeMaker's META.yml generation adding the YAML
document header to the metafile.  That's the "--- #YAML:1.0" thing.
I rejected it because its optional in YAML and just clutter in a short
document like META.yml.

But I've noticed that nowhere else in the META.yml spec does it attempt to
specify the format of the YAML file.  Everywhere else the formatting rules 
are left to the YAML spec.  Mentioning the document header is then something
of an unnecessary inconsistency and should probably be removed.

 The first line of a META.yml file should be a valid YAML document header 
 like "--- #YAML:1.0".

That line.
