Fix VM::ALL, add missing techniques to flag_to_string and replace COUTs with debug(...)

[D00Movenok]

Hi there!

Thank you for this awesome project. To make it better, I made some bug fixes:

• VM::ALL missed RDTSC and RDTSC_VMEXIT techniques, so I've added them;
• flag_to_string function missed a lot of new techniques, so I've appended them;
• Some functions used cout << instead of debug(...), so now they use debug(...).

I hope, 2 first fixes are easy to understand, but the last one needs some explanation: actually, in your lib debug() and core_debug() macroses can be replaced with end-user's debugging library, so if you use cout, it won't work.

Also I have a question about VM::ALL - maybe it also must enable VM::SPOOFABLE flag, because without it not all techniques are executed?

Hi there!

Thank you for this awesome project. To make it better, I made some bug fixes:

* `VM::ALL` missed `RDTSC` and `RDTSC_VMEXIT` techniques, so I've added them;

* `flag_to_string` function missed a lot of new techniques, so I've appended them;

* Some functions used `cout <<` instead of `debug(...)`, so now they use `debug(...)`.

I hope, 2 first fixes are easy to understand, but the last one needs some explanation: actually, in your lib debug() and core_debug() macroses can be replaced with end-user's debugging library, so if you use cout, it won't work.

Hi, thanks for the PR! I'm sure it wasn't easy reading through 10k lines of my awful C++ code lol

1. I did in fact miss both RDTSC techniques
2. Again, I completely forgot to add the missing techniques for that function. Nice eye though!
3. I often forget to replace those std::couts with debug() during development, thanks for catching that one as well. They shouldn't be there in the first place.

About the VM::ALL flag, that's also something I overlooked since it's been a while I ever used this or tested this flag due to how uncommon it is for me to do anything with it. It should indeed be activating VM::SPOOFABLE.

I also appreciate the MIT update as well, that's updated automatically based on the original GPL vmaware.hpp file for each release, but thanks for the effort.
