[Buildroot] [PATCH 7/7 v4] boot/uboot: needs host-{flex,bison}

[Yann E. MORIN]

Recent U-Boot no longer ship the flex/bison generated kconfig parser, as
of commit e91610da7c8a9fe42f3e5a75f06c3d1a0cb5f815 (kconfig: re-sync
with Linux 4.17-rc4).

So, add the conditional kconfig dependencies, as we just did for the
kernel.
