clock drift with ntp test: Fix drift file parsing

- int("1.1") is an error in python; if the input is a string, it cannot
  contain decimals.

- The contents of the drift file can be negative, make sure to convert
  the number to the absolute value before comparing with 20.

clock drift with ntp: Avoid using taskset -c

Usage of -c is not portable, just create the bit mask using python/bash.

include dependencies used in those source files.

cpu_flags: Amend to CFLAGS rather than set

Do an unconditional amend to make sure that additional CFLAGS can be
added via the make command line, while retaining the CFLAGS needed for
the build.

netperf_udp test: Use utils_netperf downloading

utils_netperf has code for downloading the netperf source, should the
input path be an URL. Remove the local function for doing this, and let
utils_netperf handle it instead.

Remove CC= from Makefiles

CC= assignments makes it impossible to supply alternate CC:s from the
command line. Additionally, CC?= does not work, as CC is set to 'cc' by
default. A possible solution might be:

ifeq ($(origin CC), default)
  CC=gcc
endif

, but seeing as cc is the preferred compiler on the target, the CC
assignment seemed unneccessary in either case.

multicast_iperf: Check if iperf is installed

To avoid doing an unnecessary download and build of iperf, check if the
application is present before building.

Killing the netserver with -9 is unneccessary and will lead to a non-0
exit status. Change to -2, and move to use the more widely available
pkill command.
