cmd/internal/obj: remove Linklookup

Browse source 
It was simply a wrapper around Link.Lookup.
Unwrap everything.

CL prepared using eg with template:

package p

import "cmd/internal/obj"

func before(ctxt *obj.Link, name string, version int) *obj.LSym {
	return obj.Linklookup(ctxt, name, version)
}

func after(ctxt *obj.Link, name string, version int) *obj.LSym {
	return ctxt.Lookup(name, version)
}

Then one comment in cmd/asm/internal/asm/parse.go
was manually updated (and gofmt'ed!),
and func Linklookup deleted.

Passes toolstash-check (as a sanity measure).
