sysutils/firstboot-pkgs: Refactor examples

Some of the examples in the rc script points to older versions of ports
which are no longer in the tree. There is no change in the
dunctionality of the ports. This is just a cosmetic change.

sysutils/firstboot-pkgs: Bootstrap and update pkg unconditionally

The background of this patch is available at:
https://lists.freebsd.org/pipermail/freebsd-cloud/2020-April/000234.html

Even a `pkg -N` success, the following `pkg install` may still fail because of
the repository version doesn't match between client and server.

Therefore, unconditionally bootstrap and update pkg at firstboot to ensure pkg
and local metadata are update-to-date.

Nominate myself for the useful-use-of-cat award.

pkg detects if its stdout is a terminal and prints many 'done%' lines,
which are useful for interactive use on modern terminals, but not so
useful on a serial console; piping through cat silences these.

pkg uses "is stdin a terminal?" to decide if it's running interactively and thereby whether it should display a progress bar during downloads. While rc.d scripts have a terminal attached, for the common case of unattended installation of servers, this script is not being used interactively; so redirect stdin from /dev/null to silence the progress bars and reduce console spew.

The -q option could be used to accomplish this, but that would also
eliminate other more useful information, such as the names and versions
of packages being installed.

Fix dumb typo: Need to check if the number of rc.d scripts has changed between pre-package-installation and post-package-installation, not between pre- and pre-.

If firstboot_pkgs installs a package which contains an rc.d script, request a reboot so that any newly-installed daemons will be launched.

To prevent fallout of lowering __FreeBSD_version in releng/10.0 branch, adjust OSVERSION evaluation in ports that specifically use '100050N'.

Add firstboot-pkgs:

When the system first boots, install the pkg(8) tools (if not already
installed) and packages listed in the $firstboot_pkgs_list rc.conf
variable.

Obviously, this port is not useful after a system is already running; it is
intended to be included as part of the installation or disk image building
process.
