This patch makes a call to the ima hook ima_kexec_cmdline,
added in "Define a new IMA hook to measure the boot command
line arguments"
to measure the boot cmdline args into the ima log.

- call ima_kexec_cmdline from kexec_file_load.
- move the call ima_add_kexec_buffer after the cmdline
args have been measured.
