bpftool: Fix indent in option lists in the documentation

commit 986dec18 upstream.

Mixed indentation levels in the lists of options in bpftool's
documentation produces some unexpected results. For the "bpftool" man
page, it prints a warning:

    $ make -C bpftool.8
      GEN     bpftool.8
    <stdin>:26: (ERROR/3) Unexpected indentation.

For other pages, there is no warning, but it results in a line break
appearing in the option lists in the generated man pages.

RST paragraphs should have a uniform indentation level. Let's fix it.

Fixes: c07ba629 ("tools: bpftool: Update and synchronise option list in doc and help msg")
Fixes: 8cc8c635 ("tools: bpftool: Document and add bash completion for -L, -B options")
