ci: CTest fails in 32-bit ARM job (test binaries executed as shell scripts) #36602

🚧 At least one of the CI tasks failed. _{Task 32 bit ARM: https://github.com/bitcoin/bitcoin/actions/runs/39741631849/job/119699974970} _{LLM reason (✨ experimental): CTest failed because ARM-target test executables could not run on the host and were interpreted as shell scripts, producing syntax errors.}
