KUnit's 'hooks.o' file need to be built-in whenever KUnit is enabled
(even if CONFIG_KUNIT=m). We'd previously attemtped to do this by
adding 'kunit/hooks.o' to obj-y in lib/Makefile, but this caused hooks.c
to be rebuilt even when it was unchanged.
Instead, always recurse into lib/kunit using obj-y when KUnit is
enabled, and add the hooks there.
Fixes: 7170b7ed6a ("kunit: Add "hooks" to call into KUnit when it's built as a module").

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.
