Note that 'proc_path' parameter in __igt_lsof_fds receives a string
which was initialized with the size of PATH_MAX and the local variable
'path' has the same size, but it also have to append: '/', '\0', and the
directory name. This situation caused the warning described below.
warning: ‘%s’ directive output may be truncated writing up to 255 bytes
into a region of size between 0 and 4095 [-Wformat-truncation=]
snprintf(path, sizeof(path), "%s/%s", proc_path, d->d_name);
note: ‘snprintf’ output between 2 and 4352 bytes into a destination of
size 4096 [..]
This patch fix the above problem.
