The nightly closure-box test still looks up KernelAbstractionsExt, which was removed when its methods moved into OpenCL. The lookup returns nothing, so Test.detect_closure_boxes throws a MethodError before checking the modules.

Remove that lookup and the now-unused import. The test continues to inspect OpenCL, SPIRVIntrinsics, and its three loaded extensions.

Validated the closure-box check on Julia 1.14.0-DEV.3743 with all three SPIRVIntrinsics extensions loaded.
