tools: libinput-record: print the list of quirks

Now that all device quirks are in the quirks subsystem we have to print those
instead of just the udev devices.

Since libinput-record is there to record system devices, the system-installed
quirk list is used (without any commandline overrides right now). This is
useful to capture misconfigurations or missing quirks on the host system.

Fixes https://gitlab.freedesktop.org/libinput/libinput/issues/58
