This patch adds support in ima to measure kexec cmdline args
during soft reboot(kexec_file_load).

- A new ima hook ima_kexec_cmdline is defined to be called by the
kexec code.
- A new function process_buffer_measurement is defined to measure
the buffer hash into the ima log.
- A new func policy KEXEC_CMDLINE is defined to control the
 measurement.[Suggested by Mimi]

Minor nit: looks like this could be simplified to:

	struct integrity_iint_cache iint = {};
	struct ima_event_data event_data = {.iint = &iint };

which also saves the later memset. 'hash' can also be initialized with '= 
{}'.
