[Issue-5581] Change into transitive dependency(netty.transport.native…

….unix.common) (#5623)

Motivation:

Explain why you're making this change and what problem you're trying to
solve.

Modifications:

From issue #5581, the class is exposed in the public API.
> Class io.netty.channel.unix.DomainSocketAddress is used as public
method parameter in
core/src/main/java/com/linecorp/armeria/common/util/DomainSocketAddress.java

Result:

- Closes #5581. (If this resolves the issue.)
- User can use [core]
com.linecorp.armeria.common.util.DomainSocketAddress#asNettyAddress
without adding dependency
