Suggestions to improve the documentation

[kerneis-anssi]

Thanks a lot for this tool and its detailed documentation which make it easy to get started.

A few things I noticed while following the provided instructions:

• you should add libXpm and gtk2 to the list of dependencies on https://intel.github.io/tsffs/setup/linux.html#install-local-dependencies
• https://intel.github.io/tsffs/fuzzing/compatibility.html uses test.efi to test micro-checkpoints, but the sample output ("Working...") corresponds to HelloWorld.efi from the tutorial section. It is a good thing to prefer test.efi here (since it doesn't require docker to compile), you should just update the text to mention the expected output is "4141414141414141" rather than "Working..."
• in the same section, you should use ./build.sh rather than ninja to build, otherwise the tsffs header is missing and linking fails.

Thanks for the notes, I'll incorporate these suggestions in the next docs update.
