s390/cpum_sf: Add data entry sizes to sampling trailer entry 

The CPU Measurement sampling facility creates a trailer entry for each
Sample-Data-Block of stored samples. The trailer entry contains the sizes
(in bytes) of the stored sampling types:
 - basic-sampling data entry size
 - diagnostic-sampling data entry size
Both sizes are 2 bytes long.

This patch changes the trailer entry definition to reflect this.
