Ian Wienand f3f671cf10 Fix default partition type
There was a typo in I6b819a8071389e7e4eb4874ff7750bd192695ff2 that
modified this default partition type from "0x83" to just 83.  We are
now seeing failures relating to this as sfdisk checks for a "disk
manager" when it see Id 0x53 (== 83)

     Device Boot      Start         End      Blocks   Id  System
  /dev/vda1   *        2048    26664575    13331264   53  OnTrack DM6 Aux3

Restore to 0x83
