Force coreboot mconf to create temp files in the output directory

This change partially addresses the problem with attempting to
    generate coreboot image out of tree. The configuration step fails when
    in cheroot, if the destination directory is placed in /tmp.

The problem is that the mconf package tries renaming the temporary
    file created in the local directory into the destination config file.
    If the destination root and the local directory are located on
    different file systems, the rename operation fails.

The proper fix (still upcoming) would be to identify all places where
    mconf creates temp files, and make sure that all temp files get
    created in the destination tree.

This change modifies just one location, which prevents building out of
    tree in the most common case.

Test:
      run the following in the coreboot directory in chroot:
        (coreboot) cp config.lumpy .config
        (coreboot) /bin/rm -rf /tmp/cb
        (coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb oldconfig
        (coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb

Observe the build succeed (it was failing during the config phase
      before this change)
