Subject: [PATCH 1/3] gstpluginloader: when env var is set do not fall through
 to system plugin scanner

If we set a custom GST_PLUGIN_SCANNER env var, then we probably want to use that and only that.

Falling through to the one installed on the system is problamatic in cross-compilation
environemnts, regardless of whether one pointed to by the env var succeeded or failed.
