plugins/amdgpu: Add plugin to inventory even if process has no vmas

Browse source 
Currently the plugin is added to the inventory only if there were amdgpu
mapped vmas in the target process. This makes restoring a simple process
with only an open DRM fd and some buffer objects not work.

Fix it by adding the plugin to the inventory when there were open DRM
files as well.
