plugin: fix name expansion in GST_PLUGIN_DEFINE() macro

Hi, this patch makes GST_PLUGIN_DEFINE use G_STRINGIFY() to convert the name
argument into a meaningful string. The advantage of this is that `name' can be
expanded from other macros defined in the plug-in element.

So, if I have the following:
#define PLUGIN_NAME(NAME) NAME
GST_PLUGIN_DEFINE(major, minor, PLUGIN_NAME(vaapi), ...)

this now expands to "vaapi" instead of PLUGIN_NAME(vaapi) :)

PS: sorry, the padding used to the next '\' is spaces instead of tabs. I can
change it to tabs so that to be consistent with surrounding lines.
