Add check for Linux minidump ending on bad write for exploitability rating.

Browse source 
If a crash occurred as a result to a write to unwritable memory, it is reason
to suggest exploitability. The processor checks for a bad write by
disassembling the command that caused the crash by piping the raw bytes near
the instruction pointer through objdump. This allows the processor to see if
the instruction that caused the crash is a write to memory and where the
target of the address is located.
