ci: run golangci-lint on freebsd

This could have been done by simply running

	GOOS=freebsd ./bin/golangci-lint run [options] ./...

on Linux, but some freebsd code is using cgo (i.e. is linked to C
libraries), so real freebsd environment is required.

This also fixes the issue of ignoring linter errors for Windows and
Darwin (exit 0), introduced by commit c9b108d5b38.

Fixes: c9b108d5b38 ("Bump golangci-lint to v2.0.2")
