Justin Gottula 44d36d2bf0 tools: canonicalize path first in udev_device_from_path (#592)
* tools: canonicalize path first in udev_device_from_path

This fixes a problem in which running ratbag-command with the path to a
device node symlink (e.g. /dev/logi-g502 -> /dev/input/event4), such as
one created by a udev rule, would not work correctly, due to the code
failing to resolve the symlink prior to checking for the presence of the
"/dev/input/event" prefix.

This resulted in nonsensical error messages (shown below) and the
curious inability to run ratbag-command successfully with anything but
the actual raw path to the device node itself (e.g. /dev/input/event4
would work fine, but /dev/logi-g502 would not, despite both being valid
ways of getting to the same device node).

    Error: Can't open '/dev/logi-g502': Success
    Error: Device '/dev/logi-g502' is not supported

Note that this same problem also prevented the usage of autogenerated
symlinks by udev, i.e. '/dev/input/by-id/' and '/dev/input/by-path/'.

* Update tools/shared.c
