Fix go syntax: no goReceiverType in goVar

[powerman]

Identifier after a pointer inside var() block incorrectly highlighted as goReceiverType:

let g:go_highlight_functions = 1

var (
	one = make(map[string]*wrongHERE.something)
	two *wrongHERE.something
)

Hi @powerman

Can you please send a before/after picture. Even though I've added your change, nothing has changed for me.

Sorry, it's activated by let g:go_highlight_functions = 1, not g:go_highlight_types.

And then I press Enter (notice prepared vim command line above) and got this:

Note that let g:go_highlight_functions = 1 is documented as:

Highlight function and method declarations.

So I'm not sure why you expect that to highlight url in the above example?

All these highlight settings and their interactions are so messy :-(

I'm expecting it to not highlight anything inside var(…), but it does highlight it. PR fixed that.
