Subject: [PATCH] build: deploy Linux native as libpinmame.so

PinMameDotNet P/Invokes libpinmame.so on Linux, but the linux-x64
native package ships libpinmame.so.<version> only, so Unity can't load
PinMAME (DllNotFoundException). Copy it as libpinmame.so (same
RenamedPlugins mechanism as win-x64), delete stale versioned copies,
and rename the .meta to keep its GUID and importer settings.

Written and submitted with AI (Claude); tested by Ben on Ubuntu 24.04.
