sysutils/tracker3: fix build with clang 16
Clang 16 has a new error about incompatible function types, which shows
up when building sysutils/tracker3:
../src/libtracker-sparql/bus/tracker-bus.vala:20:56: error: incompatible function pointer types assigning to 'void (*)(TrackerSparqlConnection *, GCancellable *, GAsyncReadyCallback, gpointer)' (aka 'void (*)(struct _TrackerSparqlConnection *, struct _GCancellable *, void (*)(struct _GObject *, struct _GAsyncResult *, void *), void *)') from 'void (*)(TrackerSparqlConnection *, GAsyncReadyCallback, gpointer)' (aka 'void (*)(struct _TrackerSparqlConnection *, void (*)(struct _GObject *, struct _GAsyncResult *, void *), void *)') [-Wincompatible-function-pointer-types]
((TrackerSparqlConnectionClass *) klass)->close_async = (void (*) (TrackerSparqlConnection*, GAsyncReadyCallback, gpointer)) tracker_bus_connection_real_close_async;
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Since the error occurs in vala-generated code, it does not make sense to
patch the .c file. Suppress the warning instead.
