glupload: move meta-data copy into gst-gl library

Browse source 
In some upload implementations the out buffer has more than one references,
turning the buffer not writable, so it won't be possible to modify its
meta-data.

This patch moves the meta-data copy before increasing the reference of the out
buffer.
