[Buildroot] [git commit branch/2019.11.x] package/rauc: select fw_printenv for uboot based systems

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=f9dc8cf5c760ef17fa5c731f9f2c1165d219e697
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.11.x

When operating on a uboot based system, rauc interacts with
the bootloader environment using fw_printenv and fw_setenv [1].

These commands should therefore be present on the target if
the system being built uses uboot.
