if path is passed, pick the tail

PluginLoader::loadApplet works both by passing a simple plugin
name and a full path of a plasmoid package.

However, when loading the optional C++ plugin, we have to look
in the standard plasmoid plugin path, so only consider the
tail of the path name, as is guaranteed that part is equal to
the plugin name.
