lib/igt_core: make single/simple tests use igt_exit

Currently tests that use igt_simple_main will simply call
"exit()" if they pass, making it difficult to ensure that
any required cleanup is done. At present this is not an
issue, but it will be when I submit a patch to turn off the
lowmemorykiller for all tests.
