ima: permit duplicate measurement list entries

Measurements carried across kexec need to be added to the IMA
measurement list, but should not prevent measurements of the newly
booted kernel from being added to the measurement list.  This patch adds
support for allowing duplicate measurements.

The "boot_aggregate" measurement entry is the delimiter between soft
boots.
