test_sysctl: fix up merge conflicts

Andrew,

as requested, this addresses the merge conflict present on kselftest/next on linux-next. The merge conflict was caused by Orson Zhai's patch titled, "tools/testing/selftests/sysctl: Add pre-check to the value of writes_strict" and my changes which shuffled the script around. I've made Orson's check a function, and integrated his exit strategy to restore the production sysctl writes_strict setting. To do this I've also added a PROD_SYCTL, which now users can also override through an environment variable.

These changes are also present on my linux-next 20170630-test-sysctl branch based on linux-next next20170630 [0]. If there are any questionms please let me know.
