ima: support new kernel module syscall
With the addition of the new kernel module syscall, which defines two arguments - a file descriptor to the kernel module and a pointer to a NULL terminated string of module arguments - it is now possible to measure and appraise kernel modules like any other file on the file system. This patch adds support to measure and appraise kernel modules in an extensible and consistent manner. To support filesystems without extended attribute support, additional patches could pass the signature as the first parameter.
