Subject: tests/cris: Fix some errors and potential crashes

These errors were reported by cppcheck:

tests/cris/check_openpf1.c:30: error:
Mismatching allocation and deallocation: f

tests/cris/check_openpf2.c:13: error:
Mismatching allocation and deallocation: f

tests/cris/check_stat3.c:16: error:
Buffer overrun possible for long cmd-line args

tests/cris/check_stat4.c:18: error:
Buffer overrun possible for long cmd-line args

The first two are obvious coding errors (fopen needs fclose, not close).

The last two may seem less important (nobody will start test code
with an argument of more than 1022 characters which raises a buffer
overrun). Fixing them nevertheless helps with static code checks
like those done by cppcheck.
