refactor(linux): package the service uninstaller wrapper through Tauri files

Place both uninstaller files in /usr/bin directly from the deb and rpm
`files` maps instead of having prebuild copy the wrapper over the
uninstaller sidecar and move the real binary to /usr/lib.

/usr/bin/clash-verge-service-uninstall stays the entry point that
released rpm %preun scripts and the app call, and is now
packages/linux/service-uninstall.sh itself. The real uninstaller is
packaged as /usr/bin/clash-verge-service-uninstall.real.

`files` sources cannot vary by target, while release builds run one
prebuild per Linux target, so prebuild stores the uninstaller without
the target-triple suffix. It is no longer an externalBin.
