parsers:udevadm: Ignore Metadata Capture device node

Some UVC video cameras contain metadata in their payload headers. New kernels
(4.15+) extracts that data and makes it available to the user space on a
separate video node, using the V4L2_CAP_META_CAPTURE capability and the
V4L2_BUF_TYPE_META_CAPTURE buffer queue type.

It's a new feature added by this commit:

    media: uvcvideo: Add a metadata device nodeSee kernel commit

But udev does not properly report this metadata cap in ID_V4L_CAPABILITIES
See https://github.com/systemd/systemd/commit/646876105fe1799355715839477958adf1d096fd

Instead of querying the capabilities with IOCTL if two devices are sharing the
same DEVPATH, the one with the highest MINOR device number corresponds to the
metadata device node.

test_udevadm: test for symlink_uuid property

Test that parses two device DBs including a USB storage device
that is enumerated differently after reboot. The key feature
is that the symlink_uuid remains the same so the device can be
tracked across the reboot.
