phosphor-ipmi-host: Move configuration to phosphor-ipmi-config

Witherspoon requires an dev_id.json file whose content is partially
derived from data provided by the os-release package. os-release is
updated for each commit, as some of its content (VERSION and
VERSION_ID) can be derived from `git describe`. As dev_id.json was
provided by the phosphor-ipmi-host package, every commit transitively
triggered a rebuild of phosphor-ipmi-host in order to satisfy
Witherspoon's requirements.

Always rebuilding phosphor-ipmi-host is unhelpful for several reasons:

* It needlessly reduces CI throughput, as it is likely the commits in
  question do not modify the phosphor-ipmi-host package.
* GCC suffers from what appears to be an unfixable[1] bug[2] that causes
  phoshor-ipmi-host to consume large (>5GiB) amounts of RAM when
  compiling some (at least Witherspoon) sensor configurations.

To avoid this, separate the configuration files out into
virtual/phosphor-ipmi-config and phosphor-ipmi-config packages that
phosphor-ipmi-host RDEPENDS on. Witherspoon provides an alternative
implementation in witherspoon-ipmi-config to mangle dev_id.json to its
particular requirements.

A virtual is used rather than a simple bbappends for Witherspoon, as the
bbappend approach breaks builds of machines other than Witherspoon if
Witherspoon is built first: The Witherspoon-specific dev_id.json file is
deployed in its mangled form into e.g. a Zaius image. Specifically, the
following sequence will trigger the issue:

    $ TEMPLATECONF=.../witherspoon.conf . openbmc-env
    $ bitbake obmc-phosphor-image
    $ rm -rf conf
    $ TEMPLATECONF=.../zaius.conf . openbmc-env
    $ bitbake obmc-phosphor-image
