[PATCH 2/2] sandbox: os: define referenced config symbols

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We built the sandbox/os/ subdirectory with different compiler flags
to avoid barebox headers masking system provided headers.

This also means that CONFIG_ options aren't defined, but common.c
already references two of them.

Define them manually in the Makefile for now to fix build breakage in
some configurations.
