Fix compiler warning about possibly truncated file name
list-local-devices.c:98:35: warning: ‘%s’ directive output may be truncated
writing up to 255 bytes into a region of size 52 [-Wformat-truncation=]
snprintf(fname, 63, "/dev/input/%s", namelist[i]->d_name);
Can't happen here, but rather than disable a potentially useful warning just
up the path to the max size.
