Subject: [PATCH] ccpp: ignore crashes of ABRT binaries if DebugLevel == 0

Prior this commit abrt-hook-ccpp was saved core file of any
crashed process executing program whose name starts with "abrt" in
DUMP_LOCATION.

ABRT does not check size constraints of these core files, so the files
could consume an uncontrolled amount of disk space.

Related to CVE-2015-5287
Related: #1262252
