libdrm: Use readdir instead of readdir_r to avoid build warnings

Browse source 
Building libdrm under AOSP, we see the following build warning:
external/libdrm/xf86drm.c:2861:12: warning: 'readdir_r' is deprecated: readdir_r is deprecated; use readdir instead [-Wdeprecated-declarations]
    while (readdir_r(sysdir, pent, &ent) == 0 && ent != NULL) {
           ^

Building on Linux with glibc produces the same warning.
Thus, this patch replaces readdir_r with readdir.
