bootstrap_guest.sh => install an anti-anti-dtrace kernel module

[rodionovd]

Checklist:

• Make sure pt_deny_attach still works on modern OS X systems.

  See: http://www.blendedcocoa.com/blog/2013/02/16/failing-to-update-the-pt_deny_attach-kernel-module-for-mountain-lion/

• If it doesn't: replace it with something like this: https://github.com/gdbinit/onyx-the-black-cat/blob/master/kext/antidebug.c#L72

  I'l also have to create a brand-new kernel module from this stuff (because onyx is the all-in-one solution we're now interested in right now).
