Remove abrt-hook-ccpp

[mgrabovsky]

abrt-hook-ccpp has been removed in abrt/abrt@77653d7a. The documentation should be updated to reflect that, all mentions removed and the current state of affairs described.

Can you assign this issue to me if it's still open?

@shivam5522 It is yours. The initial comment should have enough information, but feel free to ask questions if you need to know more.

So should I remove all the instances of C/C++ as all the code has been removed?
