Fix ABI break by moving PROCSIG_SLOTSYNC_MESSAGE in ProcSignalReason
Commit 15910b1c363 PROCSIG_SLOTSYNC_MESSAGE in the middle of
enum ProcSignalReason, breaking the ABI.
Fix this by moving PROCSIG_SLOTSYNC_MESSAGE to just before the last entry,
NUM_PROCSIGNALS, to restore ordering of other entries.
This increases the value of NUM_PROCSIGNALS, which technically changes the ABI.
However, since it represents the number of enum entries (not a signal reason),
and no affected third-party code is known, this change will be recorded in
.abi-compliance-history later.
Per buildfarm member crake.
