Commands "bpftool help" or "bpftool version" use argv[0] to display the
name of the binary. While it is a convenient way to retrieve the string,
it does not always produce the most readable output. For example,
because of the way bpftool is currently packaged on Ubuntu (using a
wrapper script), the command displays the absolute path for the binary:
$ bpftool version | head -n 1
/usr/lib/linux-tools/5.15.0-50-generic/bpftool v5.15.60
More generally, there is no apparent reason for keeping the whole path
and exact binary name in this output. If the user wants to understand
what binary is being called, there are other ways to do so. This commit
replaces argv[0] with "bpftool", to simply reflect what the tool is
called. This is aligned on what "ip" or "tc" do, for example.
As an additional benefit, this seems to help with integration with
Meson for packaging [0].

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.
