Use "true" not "TRUE" in one ICU function call.

This was evidently missed in commit 6337865, which generally did s/TRUE/true/ everywhere. It escaped notice up to now because ICU versions before ICU 68 provided definitions of "TRUE" and "FALSE" regardless. With ICU 68, it fails to compile. Per report from Condor. Back-patch to v11 where 6337865 came in. (I've not tested v10, where this call originated, but I imagine it's fine since we defined TRUE in c.h back then.)
