s390-tools: add hsavmcore utility

Browse Source 
hsavmcore is designed to make the dump process with kdump more efficient.
With hsavmcore, the HSA memory that contains a part of the production
kernel's memory can be released early in the process. Depending on the size
of the production kernel's memory, writing the dump to persistent storage
can be time consuming and prevent the HSA memory from being reused
by other LPARs.
