selftests/sched_ext: Fix unused-result warning for read()

The read() call in run_test() triggers a warn_unused_result compiler
warning, which breaks the build under -Werror.

Check the return value of read() and exit the child process on failure to
satisfy the compiler and handle pipe read errors.
