lang/go*: Update to Go 1.22 snapshot

• Add overridable BUILD_DEPENDS on shells/bash, but only for Go 1.22+
• Since lang/go121 also depends on it, allow SHEBANG_FILES to be overridden
• Re-roll the patch
• Update lang/go120 to co-exist with lang/go-devel update
• Update lang/go121 to co-exist with lang/go-devel update
