ima: Introduce per binary measurements list type binary_runtime_size value

Make binary_runtime_size as an array, to have separate counters per binary
measurements list type. Currently, define the BINARY type for the existing
binary measurements list.

Introduce ima_update_binary_runtime_size() to facilitate updating a
binary_runtime_size value with a given binary measurement list type.

Also add the binary measurements list type parameter to
ima_get_binary_runtime_size(), to retrieve the desired value. Retrieving
the value is now done under the ima_extend_list_mutex, since there can be
concurrent updates.

No functional change (except for the mutex usage, that fixes the
concurrency issue): the BINARY array element is equivalent to the old
binary_runtime_size.
