[libvirt] [PATCH v3 3/5] tests: Add test case for QEMU pci-hostdev hotplug

From: Shivaprasad G Bhat <sbhat(a)linux.vnet.ibm.com&gt; This patch adds hostdev test cases in qemuhotplugtest.c. Note: the small tweak inside virpcimock.c was needed because the new tests added a code path in which virHostHasIOMMU() (virutil.c) started being called, and the mocked '/sys/kernel/' prefix that is mocked in virpcimock.c wasn't being considered in the opendir() mock. An alternative to avoid these situations in virpcimock.c is implemented in the next patch.
