expat: fix host build issue with docbook

Additionally to the fix issued for #6923, we need to disable the docbook
usage also for the host build. This prevents the following error:

checking for docbook2man... docbook2man
configure: error: Your local docbook2man was found to work with SGML rather
  than XML. Please install docbook2X and use variable DOCBOOK_TO_MAN to point
  configure to command docbook2x-man of docbook2X.
  Or use DOCBOOK_TO_MAN="xmlto man --skip-validation" if you have xmlto around.
  You can also configure using --without-docbook if you can do without a man

speedtest-netperf: new package to measure network performance

The speedtest-netperf.sh script measures the network throughput while
monitoring latency under load and capturing key CPU usage and frequency
statistics. The script can emulate a web-based speed test by downloading
and then uploading from an internet server, or perform simultaneous
download and upload to mimic the stress of the FLENT test program.

It simplifies tasks such as validating ISP provisioned speeds or setting
up and fine-tuning SQM, directly on the router. The CPU usage details
can also help determine if the demands of SQM, routing and other tasks
such as the test itself are exhausting the device's CPUs.

This script leverages earlier scripts from the CeroWrt project used for
bufferbloat mitigation, betterspeedtest.sh and netperfrunner.sh. They are
used with the permission of the author, Rich Brown.

libseccomp: workaround a recursive dependency

DEPENDS:=@!arc is causing a recursive dependency because of the optional
selection of libseccomp by util/lxc.  The workaround hides the package
in Package/libseccomp/config instead.

lxc: Disable use of unwanted libraries explicity

Otherwise one gets a failure if the libraries (e.g. Python
header file) exist in the build system.  Worse in some cases
is host headers being found if one doesn't specifically
disable a library search in autotools.  It is especially
important that Python is disabled by default.
