42ee31e doc: fix broken bpftrace installation link (jayvaliya)

Pull request description:

  The bpftrace project has moved from the `iovisor` organization to its own
  `bpftrace` organization on GitHub. The old installation documentation link
  (`https://github.com/iovisor/bpftrace/blob/master/INSTALL.md`) is now broken (404).

  The project also restructured their documentation - installation instructions
  are now in the README.md under the "Quick Start" section rather than a
  separate INSTALL.md file.
