catalyst: Set jobs/load-average via catalyst.conf

We currently have two mechanisms of setting MAKEOPTS: in spec files and
in catalystrc.

Setting makeopts in spec files doesn't make sense. The spec should
describe the thing that's being built and not contain options that are
specific to the build system.

Setting makeopts via catalystrc is better, but it only applies to the
actual build system invocations, leaving emerge to run jobs serially or
again requiring configuration specific to the build machine to be put
into the spec file. For example:

        update_seed_command: ... --jobs 5 --load-average 5

With jobs and load-average specified in catalyst.conf, catalyst has the
information required to configure both emerge and the build systems
emerge executes.

This removes the undocumented makeopts spec file option and replaces it
with jobs and load-average settings in catalyst.conf.
