docs: binfmt-misc: Fix .rst formatting

"name below" is not part of the /proc path and should not be formatted
in monospace.

"doesn``t" is rendered in HTML with a double backtick. Revert it back to
"doesn't".

docs: Add reference in binfmt-misc.rst

While looking at the binfmt-misc documentation I noticed that there is a
reference to the “java” example that could be a direct link.

This patch simply adds the link without changing the HTML output.

docs: admin-guide: binfmt-misc: Improve the title

Trim the title a bit, since it's relatively long. Add `binfmt_misc` to
make it easier to search for the feature by its common name.

docs-rst: create an user's manual book

Place README, REPORTING-BUGS, SecurityBugs and kernel-parameters
on an user's manual book.

As we'll be numbering the user's manual, remove the manual
numbering from SecurityBugs.
