[libvirt] [PATCH] Fix 'make check' after commit 04197350

[Jim Fehlig]

I broke 'make check' with commit 04197350 by unconditionally
emitting 'hap=' in xen xm driver.  Only emit 'hap=' if
xendConfigVersion >= 3.  I've tested sending 'hap=' to a Xen 3.2
machine without support for hap setting and verified that xend
silently drops the unrecognized setting.
