introduce PARALLEL_JOBS build system variable

BR2_JLEVEL currently is expanded directly in $(MAKE), and used in
invocations of other build software (e.g. ct-ng).  However, we are
going to allow "0" to be a meaningful value for BR2_JLEVEL, which
won't work for these uses.  Given that it is not permissible to modify
BR2_-prefixed variables in Makefiles, we need an intermediate
variable.

Define PARALLEL_JOBS to $(BR2_JLEVEL), and use the former in MAKE's
definition.  Uses of BR2_JLEVEL throughout the rest of the tree to be
adjusted similarly in follow-up patches.

automatically set PARALLEL_JOBS when BR2_JLEVEL is 0

When BR2_JLEVEL is 0, set PARALLEL_JOBS to double the number of CPUs
detected.  This allows one to more or less fully utilize the host
system without manually tuning the configuration.

Also make 0 the default value for BR2_JLEVEL.

module-init-tools: don't build static tools for host

As pointed out on IRC, the static tools causes problems on distributions
without glibc-static, and we don't need them - So just disable them like
we do for the target build.

imagemagick: use alternate download location

The official ImageMagick site only keeps the latest versions. Even in
the legacy/ directory, they only keep the last version of each
'branch'. Therefore, to avoid problems, we use an alternate download
site.
