ci: install golangci-lint from source

using pre-built binaries absolutely *can* bite, e.g. in case of
env/compile-time Go version mismatch (think golangci-lint built with
go1.18 vs ran with go1.19 that is present in the env), which is why from
now on it is going to be built right in the environment where it's going
to be used with whatever version of Go is present there, that *will*
guarantee it's able to run there.

why the golangci-lint project (used to) discourage installation from sources
(or using `go install`) is still beyond me (yeah, Reasons).
