Remove Robert Young's github handle from CODEOWNERS

Robert Young's old github handle (rwy0717) was changed (to rwy7) at some
point. However, because this change was not updated in Eclipse, github
currently complains that the CODEOWNERS file has errors.

This commit removes Robert Young's github handle from the CODEOWNERS
file; it can be added back in once the necessary Eclipse changes are
made.
