package/gst1-plugins-bayer2rgb-neon: fix plugin install

- fix plugin install path, add '-with-plugindir=/usr/lib/gstreamer-1.0',
  otherwise the plugins are installed with duplicated build path
  (as detected by step_check_build_dir)

- remove GST1_PLUGINS_BAYER2RGB_NEON_INSTALL_STAGING (no need to install
  the plugin to staging)
