Add a testcase that verifies that kexec correctly logs the

This test must be run standalone, since it runs kexec
multiple times (and therefore reboots several times).
Verifying the kexec boot command line doesn't require rebooting. Just
loading the kexec kernel image should be enough (kexec -s -l).
Verifying that the measurement list, including the kexec boot command
line, is carried across kexec could be a separate test.
This is true. However, it only appends to the IMA log once, even if you
unload (`kexec -u`) the kexec kernel after `kexec -s -l ...`.
Therefore, the test would only be able to check kexec with the cmdline
supplied in one way.
I will have to check internally if that's the right way to go. If it
didn't need to reboot, then the test could be integrated into the normal
IMA tests,
which would definitely be a good thing.
