util/abuild: Use realpath for FAILED_BOARDS/PASSED_BOARDS

The abuild script will `cd` into the build directory. FAILED_BOARDS
defaults to a relative path, so it ends up trying to echo into a
directory that doesn't exist.

If we set the realpath to the file then we can correctly update the
failed/passed boards file.

BUG=none
TEST=make what-jenkins-does and verified there was a failed_boards and
passed_boards in coreboot-builds.
