build: configure ldflags to enable compilation with go 1.23 (artela-n…

…etwork#5)

Quote from memsize README:
> NOTE: As of Go 1.23, memsize no longer works because of a restriction added by the
> Go toolchain. The Go 1.23 compiler no longer allows access to runtime symbols via
> go:linkname, which prevents memsize from accessing the Stop-the-World
> functionality of the Go runtime.
>
> If your program depends on memsize, you can disable the restriction when building
> your program:
>
>    go build -ldflags=-checklinkname=0

As build is managed by ignite, the configuration in config.yml was altered to
set proper ldflags.
