rtla: Add Documentation
Adds the basis for rtla documentation. This patch also includes the rtla(1) man page. As suggested by Jonathan Corbet, we are placing these man pages at Documentation/tools/rtla, using rst format. It is not linked to the official documentation, though. The Makefile is based on bpftool's Documentation one.
