GH-45455: [GLib] Fix returns positive memory-pool utilization (#45456)

### Rationale for this change Due to byte_allocated size returning 0, The TestMemoryPool-only test failed. This issue did not occur when running other tests together because the other tests use the memory pool. ### What changes are included in this PR? Allocate a ResizableBuffer in the TestMemoryPool test. ### Are these changes tested? Yes. ### Are there any user-facing changes? No. * GitHub Issue: #45455 Lead-authored-by: Hiroyuki Sato <[email protected]> Co-authored-by: Sutou Kouhei <[email protected]> Signed-off-by: Sutou Kouhei <[email protected]>
