[Xen-devel] [PATCH] build: use correct qemu path in systemd service file and init script

[Ting-Wei Lan <lantw44@xxxxxxxxx>]

When --with-system-qemu is used, it is possible that we cannot find
qemu-system-i386 in LIBEXEC_BIN, which can cause error in xencommons
init script and xen-qemu-dom0-disk-backend.service systemd service.
