The "ima: add support for arch specific policies" patch set introduced
architecture specific policies, including an x86 policy which prevents
loading a kernel image via the kexec_load syscall.
This patch set preq's that patch set, adding a missing kexec_load
syscall failure message, extending the existing support for detecting
secureboot mode, and defining a kexec_load syscall selftest to
simplify testing.
To run the kexec_load test requires root privileges.  Execute:
	"sudo make TARGETS=ima kselftest".
With secure boot enabled, the kexec_load fails, but the test
succeeds.
selftests: ima: test_kexec_load.sh
========================================
./test_kexec_load.sh: kexec_load failed [PASS]
ok 1..1 selftests: ima: test_kexec_load.sh [PASS]
