signald: reduce closure size by switching to a custom JRE bundle
This effectively reduces the size of the runtime closure by ~79%:
$ nix path-info ./result-old -Sh
/nix/store/9ggmj6fmqszfvd0lg2im7qssscql0jac-signald-0.15.0 729.0M
$ nix path-info ./result -Sh
/nix/store/z9bfj547j9fkyl8g0mqb1n108s7zw4w5-signald-0.15.0 155.2M
Similar change as 2f9426ad8312101f4e84bcc4e28860695d28005f: newer Java
versions don't support a "traditional" JRE anymore, but it's possible to
create dedicated runtime environments using `jlink`[1].
