Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Explicitly set CXXSTD to c++11 for old C++ code using std::auto_ptr<>.

GCC 12 defaults to C++17 which removes (not just deprecates)
std::auto_ptr<>. Trying to use CXXSTD of c++03 doesn't work with
libc++ headers, but c++11 does.

Simplify and speed up the kyua build

Instead of having multiple kyua libraries, just include the files as part
of usr.bin/kyua. Previously, we would build each kyua source up to four
times: once as a .o file and once as a .pieo. Additionally, the kyua
libraries might be built again for compat32. As all the kyua libraries
amount to 102 C++ sources the build time is significant (especially when
using an assertions enabled compiler). This change ensures that we build
306 fewer .cpp source files as part of buildworld.

Install a kyua.conf based on the one in devel/kyua.

The kyua.conf from examples doesn't match the expected config and
contains a lot of undesirable entries such as setting the architecture
to amd64 explicitly.

Fix build with src on a noexec filesystem.

${SH} expands to nothing on src builds so this worked by accident. Use
a bare "sh" instead.

Revert r359385-r359387

As noted by brooks/emaste, this is the wrong approach to take.
Revert the changes so brooks can apply a more proper change.

Check in the generated copies of the manpages

These manpages were meant to be templated once per `configure` run.

Given that we're not bound by as many constants, e.g., `--prefix` isn't
generally changing for kyua in the base system, having to generate the
manpages each build seems slightly less than optimal.

In the event that one's build environment doesn't define `$SH`, the build
will also fail until this change is introduced.

Instead of jumping through hoops dealing with shells or permissions, let's
just cut to the chase and check the generated copies into the sourcebase
under usr.bin/kyua .

Install expected kyua docs.

The "kyua about" command assumes these files exist causing tests
supplied devel/kyua to fail.

Fix a bug defining the default KYUA_DOCDIR so the installed files can be
found.
