go-native: rename to go-initial-native

With the new per recipe sysroots we were having build issues since the
bootstrap version of go (go-native 1.4) was being found and not the
go-cross (1.6) we are expecting. This results in errors such as the
following when building packages such as containerd:

  _cgo_.o: decoding dwarf section info at offset 0x4: unsupported version 0

This is caused by the dependency tree built up to prepare the per
recipe sysroot. Since recipes like containerd DEPEND on go-cross and
go-cross DEPENDS on go-native both are installed but unlike the old
global sysroot the dependency parsing order results in go-native being
last, overwriting go-cross. You can see this by running a devshell for
containerd and running 'go version'.

By adding '-initial' in the name we exploit functionality in
sstate.bbclass that is already in place to handle gcc-initial and
similar. This results in only explicit DEPENDS on go-native being
enforced, so in the case of containerd we only get a dependency on
go-cross and we therefor get go 1.6 as expected.
