virsh-dump: Add Crash Utility Tests for vmcore

This Patch adds support for testing Crash Utility
for vmcore generated by "virsh dump" command.

Crash Utility is a tool that allows us to interactively analyze a running Linux system as well as a core dump created.

This crash_utility function works as following:
Check the working of crash utility tool to analyse the guest dump In order for the function to work, both the guest and the host must have the same kernel

• If crash tool or kernel debug libraries are not installed, the test returns error
• If crash tool cannot read into the vmcore, the test returns fail
• If crash tool can read the vmcore, the test returns pass

The Function returns:
0: Success
1: Crash command failed
2: Dependency installation failed or vmlinux not found
3: Kernel mismatch between host and guest
4: Guest kernel retrieval failed
5: Unsupported distribution
6: virsh dump unsuccessful
