Rename pg_shdepend.c's typedef "objectType" to SharedDependencyObjectType.

The name objectType is widely used as a field name, and it's pure luck that
this conflict has not caused pgindent to go crazy before.  It messed up
pg_audit.c pretty good though.  Since pg_shdepend.c doesn't export this
typedef and only uses it in three places, changing that seems saner than
changing the field usages.

Back-patch because we're contemplating using the union of all branch
typedefs for future pgindent runs, so this won't fix anything if it
stays the same in back branches.
