Bug find in exec rkt run, test result of rkt is not correct yet, because rkt can not return the error code from the entry process,.
The bug will cause wrong success result of testing rkt.
I and @wangkirin just fixing the bug.

@liangchenye @wangkirin I have fixed the bug in my local git registry, using the another way of "rkt status" to replace using return code of "rkt run".

But I find another problem in using ocitool in the situation of rkt, just thinking about how to fix it.

@wangkirin Can u fix the bugs on ocitools/cmd/runtimetest to support RKT?

It is not support RKT yet, if u can fix it , it should be very nice.

@liangchenye @wangkirin The supporting of rkt have been work properly, but we have to fix some bugs in ocitools for rkt supporting later.

@zenlinTechnofreak Cool!

Do you plan to announce the OCT progress to OCI?
