docs: bpf: Rename README.rst to index.rst

Recently bpf/ docs were converted to use RST format.  'README.rst' was
created but in order to fit in with the Sphinx build system this file
should be named 'index.rst'.  Rename file, fixes to integrate into
Sphinx build system in following patches.

docs: Rename Documentation/bpf/README.rst to Documentation/bpf/index.rst

-=================
-BPF documentation
-=================
-
-This directory contains documentation for the BPF (Berkeley Packet
-Filter) facility, with a focus on the extended BPF version (eBPF).
-
-This kernel side documentation is still work in progress.  The main
-textual documentation is (for historical reasons) described in
-`Documentation/networking/filter.txt`_, which describe both classical
-and extended BPF instruction-set.
-The Cilium project also maintains a `BPF and XDP Reference Guide`_
-that goes into great technical depth about the BPF Architecture.
-
-The primary info for the bpf syscall is available in the `man-pages`_
-for `bpf(2)`_.
-
-
-
-Frequently asked questions (FAQ)
-================================
-
-Two sets of Questions and Answers (Q&A) are maintained.
-
-* QA for common questions about BPF see: bpf_design_QA_
-
-* QA for developers interacting with BPF subsystem: bpf_devel_QA_
