linux: select host-uboot-tools with FIT on mips

In the latest kernel, FIT images are always generated when building a
kernel for MIPS. Note that we build the kernel with:

  make all
  make <selected-image>

so the selected image through Buildroot options doesn't matter: a FIT
image is always generated.

Therefore, in order to fix autobuilder issues, make sure
host-uboot-tools with FIT image are always selected when building the
latest kernel version. We do not select it in general as custom
versions may be different.
