Felix Maurer 8c0be0631d selftests: bpf: Fix bind on used port 
The bind_perm BPF selftest failed when port 111/tcp was already in use
during the test. To fix this, the test now runs in its own network name
space.

To use unshare, it is necessary to reorder the includes. The style of
the includes is adapted to be consistent with the other prog_tests.

v2: Replace deprecated CHECK macro with ASSERT_OK

Fixes: 8259fdeb30 ("selftests/bpf: Verify that rebinding to port < 1024 from BPF works")

README 

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.
