As part of libbpf in5e61f27070("libbpf: stop enforcing kern_version, populate it for users") non-LIBBPF_API __bpf_object__open_xattr() API was removed from libbpf.h header. This broke bpftool, which relied on that function. This patch fixes the build by switching to newly added bpf_object__open_file() which provides the same capabilities, but is official and future-proof API. v1->v2: - fix prog_type shadowing (Stanislav).

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.
