PR4886: check build-id if able.
This provides sanity check of debuginfo file based on build-id. Many cases are considered, whether build-id exists in debuginfo file or not, whether module is loaded or not, whether build-id exists in runtime kernel/module. It will do work when LD >= 2.18 and kernel >=2.6.23, otherwise no check.
