[OE-core] [PATCH] oe-buildenv-internal: Add UBOOT_CONFIG to environment whitelist

[Otavio Salvador]

The uboot-config class uses the UBOOT_CONFIG environment setting to
choose which U-Boot option is intended to build. It is convenient to
allow it to be set from the shell, as supported for MACHINE.

This allow, for example, to trigger a build as:

,----
| MACHINE=imx28evk UBOOT_CONFIG=nand bitbake core-image-minimal
`----
