MacOS SDK needs to be bumped to version 12 for Golang 1.25.x images #662
Description
When trying to use the docker.elastic.co/beats-dev/golang-crossbuild:1.25.1-darwin-debian11 image for building Beats with Golang 1.25.1, we are seeing the following error:
/usr/local/go/pkg/tool/linux_amd64/link: running o64-clang failed: exit status 1

Reading through the Go 1.25 release notes, specifically https://go.dev/doc/go1.25#darwin:
As announced in the Go 1.24 release notes, Go 1.25 requires macOS 12 Monterey or later. Support for previous versions has been discontinued.
And it looks like we're still using either the 10.11 or 11.3 MacOS SDK in golang-crossbuild images. So these SDK versions should probably be updated to version 12.
