Subject: Try kexec_load(2) if kexec_file_load(2) fails for any reason
References: bsc#1080916
Upstream: merged
Git-commit: c9f231320fe6544b4e8aedd24a571105c4ff458a

Currently, kexec_load(2) is attempted only if kexec_file_load(2) is
unavailable. However, kexec_file_load(2) may also fail for other
reasons (e.g. missing kernel signature). It makes sense to try the
older syscall in that case.
