Re: [libvirt] [PATCH 08/18] virpcimock: Create devices/ and drivers/ under /sys/bus/pci upfront

In near future, we will be creating devices under different
location and just symlink them under devices/. Just like real
kernel does. But for that we need the directories to exists.

nit: s/exists/exist

make_dir could also be used to create the tmp directory as well, like
make_dir(fakerootdir, SYSFS_PCI_PREFIX), getting rid of all the
virFileMakePath() calls inside init_env(). Not worth rerolling the patch
just because of that though.
