go: drop the old 1.4 bootstrap C version

Bootstrap [1]
As mentioned in the Go 1.20 release notes, Go 1.22 now requires the final point release of Go 1.20 or later for bootstrap.
We expect that Go 1.24 will require the final point release of Go 1.22 or later for bootstrap.

The default recipe for bootstrap is the go-binary-native as can be seen in:
meta/conf/distro/include/tcmode-default.inc:68:PREFERRED_PROVIDER_go-native ?= "go-binary-native"

Currently if we change it to use the old go-native and compile the go1.4-bootstrap-20170531
it fails:

| Building Go cmd/dist using /build/workdir/tmp-glibc/work/x86_64-linux/go-native/1.22.3-r0/go1.4/go. (go1.4-bootstrap-20170531 linux/amd64)
| can't load package: package ./cmd/dist: found packages build.go (main) and notgo120.go (building_Go_requires_Go_1_20_6_or_later) in /build/workdir/tmp-glibc/work/x86_64-linux/go-native/1.22.3-r0/go/src/cmd/dist

This has been broken for some time but as we used go-binary-native by default it went unnoticed.
