When run tests with 2 VMs, for example nfs/ssh kdump tests, client VM will do the
crash and dump, server VM will do vmcore saving and if-vmcore-exists
check.
Previously, when client VM finishes running, run-test.sh will kill the lead background
process, and then check if server VM has outputted "TEST PASSED" or "TEST FAILED" string.
However it didn't wait for server VM to finish. As a result, the server VM's final
outputs are not collected and checked, leaving the test result as "TEST RESULT NOT FOUND"
sometimes.
For example, the following is the pstree status of $(jobs -p) before it
gets killed. We can see the server VM is still running:
run-test.sh,172455 /root/kexec-tools/tests/scripts/run-test.sh --console nfs-early-kdump
└─run-test.sh,172457 /root/kexec-tools/tests/scripts/run-test.sh --console...
└─timeout,172480 --foreground 10m /root/kexec-tools/tests/scripts/run-qemu...

├─{qemu-system-x86},172628
└─{qemu-system-x86},172629
In this patch, we will wait for $(jobs -p) to finish, in order to get
the complete output of test results.
