build(common): switch from external libp2p to local p2p module

Replace the Maven dependency on io.github.tronprotocol:libp2p:2.2.7
with a project dependency on the local :p2p module. This eliminates
11 exclude rules that were needed for the external artifact and
removes the libp2p entry from dependency verification metadata.

java-tron no longer depends on any external libp2p artifact.
