Kovacsics Robert 2c8c8f2961 wrapGAppsHook: don't add empty variables
Adding empty variables can lead to this problem:

```diff

```
Where the diff is to highlight the problem: we don't have a valid value
for GST_PLUGIN_SYSTEM_PATH_1_0 or GRL_PLUGIN_PATH, and instead of
passing the empy string, the empty string gets unquoted somewhere, so we
end up passing no arguments, thus the parser in wrapProgram takes
--prefix as the argument of GST_PLUGIN_SYSTEM_PATH_1_0, and then
GI_TYPELIB_PATH is missing it's --prefix so wrapProgram complains/dies.

The easiest change is to not add empty arguments to the wrapper
