build: accommodate new syntax-check test

Use EXIT_FAILURE and EXIT_SUCCESS, not 1 and 0.
Apply these commands:
perl -pi -e 's/\berror \(1,/error (EXIT_FAILURE,/' \
  $(git grep -l '\<error (1,')
perl -pi -e 's/\bexit \(1\)/exit (EXIT_FAILURE)/' \
  $(git grep -l '\<exit (1)')
perl -pi -e 's/\bexit \(0\)/exit (EXIT_SUCCESS)/' \
  $(git grep -l '\<exit (0)')
