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)
• Remove CMAKE_VERBOSE, NINJA_VERBOSE and CONFIGURE_ARGS=--disable-silent-rules from all ports which set them for this is no longer needed
• Revert hacks for --disable-silent-rules support priorly committed to biology/ncbi-blast+ and net-p2p/mldonkey - no longer needed as well
