Use monotonic time

To measure launching time properly, we should use monotonic time.

Requires:
 - https://review.tizen.org/gerrit/#/c/platform/core/appfw/aul-1/+/220595/
 - https://review.tizen.org/gerrit/#/c/platform/core/appfw/amd/+/220598/
 - https://review.tizen.org/gerrit/#/c/platform/core/appfw/launchpad/+/220600/
