Make xtrct_small_copy_dir optional parameter

The job that builds SDK’s requires this option.
build-setup.sh defaults to copying the normal
obmc-phosphor-image bitbake artifacts out of
the build directory. The SDK artifacts are
stored in a different directory so the jobs
which build SDK's needs a way to tell
build-setup.sh where to copy these artifacts
from.
