Fix gnu-folding-constant warning.

j2objc-copybara · copybara-github · commit 46c02a01a477 · 2025-06-16T07:59:41.000-07:00
Xcode 26 beta 1 drops -Wno-gnu-folding-constant, which means at least some teams now get -Wgnu-folding-constant behavior. This CL fixes the one (known) violation in J2ObjC code.
