[PATCH evemu 1/2] Fix compiler warning about truncated output

[Peter Hutterer]

It's a false positive because we only ever print /dev/input/eventXX but let's
shut it up anyway.

find_event_devices.c: In function ‘find_event_devices’:
find_event_devices.c:65:9: warning: ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size 53 [-Wformat-truncation=]
     "%s/%s", DEV_INPUT_EVENT, namelist[i]->d_name);
         ^~
find_event_devices.c:64:3: note: ‘snprintf’ output between 12 and 267 bytes into a destination of size 64
   snprintf(fname, sizeof(fname),
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     "%s/%s", DEV_INPUT_EVENT, namelist[i]->d_name);
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
