Fix -K check. The -K check is not currently very useful, and was incomplete: |skip_remount| was being set to 1 even in the cases where the remount was happening with different flags (and therefore not being skipped.) Fix this by renaming the |skip_remount| variable to |change_remount| so that it better reflects what we want to test, and adding a clearer error message (with a suggestion to explicitly add '-v'.) Also fix some long lines and a comment. Bug: chromium:1008895 Test: Unit tests pass. Test: minijail0 -p -K -- /bin/id prints error. Test: minijail0 -p -Kslave -- /bin/id prints error. Test: minijail0 -pv -K -- /bin/id runs successfully. Test: minijail0 -pv -Kslave -- /bin/id runs successfully. Change-Id: I19b4bf4f495bd5ec40338f2502854d4054be4c5c

Minijail is a sandboxing and containment tool used in Chrome OS and Android. It provides an executable that can be used to launch and sandbox other programs, and a library that can be used by code to sandbox itself.
