meta-phosphor: ipmid: enable EXTRA_OECONF override

Set the whitelist with the post-parse append operator, so ipmid
bbappends can set EXTRA_OECONF directly.

A simple example illustrates how this helps:
 foo.bb:
  BAR = "def"
  FOO = "abc ${BAR}
 foo.bbappend:
  FOO = "zyx"

FOO would be "zyx"  But if one has:
 foo.bb:
  BAR = "def"
  FOO = "abc"
  FOO_append = " ${BAR}"
 foo.bbappend:
  FOO = "zyx"

FOO would be "zyx def"

This is because bitbake parses recipes and bbappends in multiple
passes - the second pass is when things like the _append operator
and inline python are evaluated.
