Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

net-mgmt/adcli: Fix plist to pass testport

Approved by:	portmgr (with hat)
MFH:		2017Q4

Most commonly used build systems support silent builds, when they
hide actual commands executed and only show short summary line (like
"CC foo.c"). CMake and ninja enable this by default, some autotools
using ports do as well. This is unacceptable because we need complete
build logs at any time, so we now switch to verbose build logs
unconditionally. Note that this change deliberately affects ALL
builds and not only package builds on cluster, because we need to
be sure that user experiencing failure can always provide informative
build log regardless of settings and without rerunning the build.

Change summary:

- Always do verbose builds for cmake, ninja and GNU configure (the
  latter includes check if --disable-silent-rules is actually supported
  by the configure script; there are isolated cases when it's not true)

Add docbook stuff to BUILD_DEPEND, otherwise build may die, when
generating the utility's man-page.
