[aur-general] Merge request for [xen-4.3].

Please merge xen-4.3[1] into xen-4.3-git[2]. Reasoning: - There are only minor differences between the two PKGBUILD files. - Both packages retrieve their sources with Git. - Both packages were submitted by the same user, suggesting that the uploading of xen-4.3-git was a rename attempt. - xen-4.3 is unmaintained.
