test: add two path tests for invalid devices

Browse source 
One test for an actual file (so far we only tested /tmp, the directory) and
one for a kernel dev that returns a udev device and thus gets one step further
in the error handling code.

Plus, I saw test code doing this (opening /dev/uinput) and it crashed (for
other reasons), so we might as well test it.
