Add a selftest demonstrating using detach-mounted BPF FS using new mount APIs, and pinning and getting BPF map using such mount. This demonstrates how something like container manager could setup BPF FS, pin and adjust all the necessary objects in it, all before exposing BPF FS to a particular mount namespace. Also add a few subtests validating all meaningful combinations of path_fd and pathname. We use mounted /sys/fs/bpf location for these.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
