    buildhistory.bbclass: do not influence sstate of do_rootfs
    
    Enabling or disabling buildhistory caused a rebuild of images, which
    is undesirable. For example, it prevented image reuse from a main
    build with buildhistory in a following oe-selftest where buildhistory
    must be disabled.
    
    The reason are the additional ROOTFS_POSTUNINSTALL_COMMAND and
    ROOTFS_POSTUNINSTALL_COMMAND entries. Those need to be excluded both
    via vardepvalueexclude and vardepsexclude.
