When collecting plugins required for the android application according
to linked targets we should take into account all prefix directories.
But not only the first one. Otherwise the order we use when adding
paths to extraPrefixDirs will affect collecting of the plugins. This
specifically leads to the issue if the user project builds custom Qt
plugins. The plugin directory from user project build tree will be
found first and all plugins from Qt installation directory are
discarded.
