bpf, docs: Fix final bpf docs build failure

Browse Source 
maps.rst in the BPF documentation links to the
/userspace-api/ebpf/syscall document
(Documentation/userspace-api/ebpf/syscall.rst). For some reason, if you
try to reference the document with :doc:, the docs build emits the
following warning:

./Documentation/bpf/maps.rst:13: WARNING: \
    unknown document: '/userspace-api/ebpf/syscall'

It appears that other places in the docs tree also don't support using
:doc:. Elsewhere in the BPF documentation, we just reference the kernel
docs page directly. Let's do that here to clean up the last remaining
noise in the docs build.

BPF maps are accessed from user space via the ``bpf`` syscall, which provides
commands to create maps, lookup elements, update elements and delete
elements. More details of the BPF syscall are available in
:doc:`/userspace-api/ebpf/syscall` and in the `man-pages`_ for `bpf(2)`_.
