    Fix ABI break by moving PROCSIG_SLOTSYNC_MESSAGE in ProcSignalReason
    
    Commit 58c1188a3ea added PROCSIG_SLOTSYNC_MESSAGE in the middle of
    enum ProcSignalReason, breaking the ABI.
    
    Fix this by moving PROCSIG_SLOTSYNC_MESSAGE to the end of the enum,
    to restore ordering.
    
    Per buildfarm member crake.
