DPD estimators such as xtabond2 do not use fixed effects; they use first differencing, which like fixed effects remove the unobserved heterogeneity in a dynamic panel. But you do not seem to have a duynamic model.
I think you can easily estimate this model with IV-GMM and fixed effects with some simple algebra and Mark Schaffer's xtivreg2 from SSC:
g double yv = y - v
g double kv = k - v
g double hv = k - v
ssc inst ivreg2, replace
ssc inst ranktest, replace
ssc inst xtivreg2, replace
xtivreg2 yv a (kv hv = z1 z2 z3 z4 z5), fe gmm2s robust
lincom v = 1 - kv - hv
