Subject: [PATCH 2/7] Add awk_exit() function

ASAN test showed exiting toybox awk via exit() caused a memory leak, because
toybox did not have a chance to do its normal cleanup. Replace calls to exit()
with awk_exit(), which sets toys.exitval and calls xexit() in toybox, but
simply calls exit() in standalone wak.
