…rading to go1.16

commit 77f2d90 introduced the slices import,
which uses generics, but failed to add the go:build directives.

    # github.com/docker/docker/daemon/logger/loggerutils
    ../../daemon/logger/loggerutils/logfile.go:770:2: implicit function instantiation requires go1.18 or later (-lang was set to go1.16; check go.mod)

commit a0807e7 configured golangci-lint
to use go1.23 semantics, which alowed linters like `copyloopvar` to lint
using thee correct semantics.

go1.22 now creates a copy of variables when assigned in a loop; make sure we
don't have files that may downgrade semantics to go1.21 in case that also means
disabling that feature; https://go.dev/ref/spec#Go_1.22
