Add a test case to check whether an unsuccessful creation of an outer map of a BTF-defined map-in-map destroys the inner map. As bpf_object__create_map() is a static function, we cannot just call it from the test case and then check whether a map accessible via map->inner_map_fd has been closed. Instead, we iterate over all maps and check whether the map "$MAP_NAME.inner" does not exist.

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.
