tests: fix match_diff usage

The first argument of match_diff should be the file with expected
output, the second argument - the file with actual output.

* tests/aio.test: Swap match_diff arguments.
* tests/restart_syscall.test: Likewise.
* tests/seccomp.test: Likewise.
* tests/umovestr2.test: Likewise.
