glupload: make nvmm upload manner only consider system memory

Browse source 
The current _nvmm_upload_transform_caps() only simply apply
"memory:NVMM" to all input caps to transform the output caps.
This is not precise and may cause problem. For example, if the
input caps include:

  video/x-raw(memory:DMABuf), width=(int)1920, height=(int)1080, \
  interlace-mode=(string)progressive, multiview-mode=(string)mono, \
  framerate=(fraction)30/1, drm-format=(string)NV12:0x0100000000000002

it will be changed as

  video/x-raw(memory:GLMemory), width=(int)1920, height=(int)1080, \
  interlace-mode=(string)progressive, multiview-mode=(string)mono, \
  framerate=(fraction)30/1, drm-format=(string)NV12:0x0100000000000002

For GLMemory kind caps, no drm-format should appear.

So we should let it only transforms which it can recognize.

And in _nvmm_upload_accept(), we should only accept the "memory:NVMM"
feature in input caps.
