lib/oeqa/runtime: smart: add checks for smart output
Sometimes smart throws:
Committing transaction...
Preparing... ######################################## [ 0%]
1:Removing psplash-default ######################################## [100%]
error: Couldn't fork %postun: Cannot allocate memory
and returns a 0 exit code (it thinks it succesfully removed the package,
when in reality it didn't), so we need to catch those specifically.
Also, sometimes output from download command is:
Saving cache...http://192.168.7.1:49456/rpm/x86_64_x32/psplash-default-0.1+git0+
afd4e228c6-r15.x86_64_x32.rpm
and that tricks our smart download test, so use a regex there.
