LOG: [Fuzzer] make big-file-copy.test work with the internal shell (#168658)

This patch uses several shell features not supported by the internal
shell, such as $? to get the exit code of a command, and exit. This
patch adjusts the test to work with the internal shell by using bash to
run the actual command with a zero exit code to ensure the file is
deleted, and python to propagate the exit code up to lit.
