[FAB-5114] Makefile fix for right version computation
[FAB-5114] Makefile fix for right version computation

peer exe follows a different metadata pattern than other exes
such as configtxgen, cryptogen etc. The fix sets GO_LDFLAGS
for each binary production so peer's GO_LDFLAGS can be different
from other binaries.

. made one scoped change for peer production per Gari's comment
