maven_update_deps: add support for custom repository mappings

Allow recipes to define custom Maven repository URL mappings via
MAVEN_REPO_URLS variable. This enables recipes to specify non-standard
repositories for their dependencies.

Format: MAVEN_REPO_URLS = "repo-id=https://url repo-id2=https://url2"
