configure.ac: enable subdir-objects

The main thing holding us back here was our gcov hacks. We used to rebuild the
libevdev sources locally inside test/ with the gcov flags so that we could
leave the main libevdev sources untouched. This doesn't work well with
subdir-objects - we have to link to libevdev.la instead.

To enable gcov, we now have to apply the gcov flags to the main library
object. But this also means that when running, the notes files will be
somewhere within the libevdev/ directory, not the test/ directory. Working

Mouse (when connected via bluetooth) we get a bunch of events at the start of

libevdev_uinput_destroy: don't close non-open FD

The returned errno from libevdev_input_create_from_device was returned
incorrectly because libevdev_uinput_destroy() would try to close the
unset value of ->fd, overwriting errno.

That was fixed in debe9b030c8069cdf78307888ef3b65830b25122, this patch avoids
the ioctl/close calls if the fd isn't set.

tools: note that the mouse frequency measured is the highest frequency

Some devices scale the frequency based on the input and will provide
recordings with different frequencies each time. Recommend to measure multiple
times since we can only know what the highest frequency is.
