lsgpu: Add filter type print-out selection

In the previous patch we switched the lsgpu output to a short and user
friendly format but some users will need a shorthand for getting other
types of device selection filters than the defaut drm.

Add some command line switches to enable this:

$ lsgpu
card0                   8086:193B    drm:/dev/dri/card0
└─renderD128                         drm:/dev/dri/renderD128

$ lsgpu --sysfs
card0                   8086:193B    sys:/sys/devices/pci0000:00/0000:00:02.0/drm/card0
└─renderD128                         sys:/sys/devices/pci0000:00/0000:00:02.0/drm/renderD128

$ lsgpu --pci
card0                   8086:193B    pci:vendor=8086,device=193B,card=0
└─renderD128

v2:
 * Fix pci filter format.
