[Buildroot] [PATCH] package/go: go-bin host-go provider implies target support

[Tom Wambold <tom5760@gmail.com>]

The BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS configuration symbol is
used to determine if we can build Go packages for the target
architecture.  Previously, this depended *only* on the
BR2_PACKAGE_HOST_GO_BOOTSTRAP_STAGE3_ARCH_SUPPORTS symbol, which is true
only if the host system can bootstrap the Go compiler.

The go-bin package makes it unnecessary to bootstrap the Go compiler.
Also, some host architectures (i.e. arm64/aarch64) don't support
bootstrapping the compiler anyway.

Add a new symbol BR2_PACKAGE_HOST_GO_BIN_TARGET_ARCH_SUPPORTS to let
BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS depend on either being
able to bootstrap the compiler *OR* using the go-bin package.  This
fixes being able to use the Go compiler to build target packages on an
arm64/aarch64 host system.
