linux: always select host-uboot-tools for mips

Browse Source 
Since Buildroot commit 40e266ccb9 [1], host-uboot-tools was always selected
for the latest Linux kernel. This change is intended for autobuilders, and
was introduced in Buildroot while the latest kernel was 6.12.

However, further investigation seem to indicate that itb images were
generated for mips for a much longer time. Linux commit eed0eabd12 [2]
seem to enable that image format, and was released in Linux 4.9.

This version being EOL for quite some time, we can therefore assume
any "not so old" Linux for mips will need host-uboot-tools to finalize
this image, and therefore we should select it when building Linux.
