miext/sync: Fix ABI change on 32bit
The newly added field `initialized` increases the size of the structure `_SyncObject` on 32bit, which is embedded in other structures, and therefore can cause a crash of the Xserver when a client tries to create a fence. To avoid changing the size of the structure, and therefore breaking the ABI, move the field back where it was initially but change its type to a 1 byte `char` instead of `Bool` which is defined as an integer.
