Make the volatiles file name start with a numeric value to unified
volatiles file naming. I searched in oe-core, only pluseaudio volatiles
file name is not start with number.
On a default sato-sdk image:
$ ls /etc/default/volatiles/
00_core 01_bootlogd 99_dbus 99_sshd 99_wpa_supplicant volatiles.04_pulse
This is just a name change and will not affect the functionality.
