qemu.tests.physical_resources_check: Fix RHEL5 compatibility

Turns out RHEL5 qemu does not support the 'info qtree'
command, therefore an attempt to parse the output of
this command will fail. So skip that particular check
when running on this particular qemu version.

virttest.qemu_vm: Fix error in string repr of MigrateError

The problem was that the arguments for the string interpolation
were not passed as a tuple, as they should. When hitting
an unknown migration protocol error, the return would raise
a TypeError. Let's fix it.

physical_resources_check: Convert exceptions to strings before concatenation

There might be an occasion where we get the following

first.

bootstrap: Create gpg directory upon data dir creation

Since a GPG file is a user provided data (like isos
and guest images), it makes more sense to have it
under shared/data/gpg than shared/gpg. So remove the
later and fix things in the bootstrap module.

virttest.qemu_devices: Use the bus function to check if it matches the spec

When we try to match a bus to some specification (dictionary) it makes
sense to ask the bus and not to try to guess. This way we can customize
the function to each bus, if necessarily.

Additionally make it possible to ignore autotest type by setting
atest=False. This could be used to see if this specification matches from
qemu point of view, but doesn't match from autotest point of view.
(from qemu point of view ahci and ide bus is the same, but in autotest
we want to make sure the ide-hd goes into the correct HBA). This feature
will be used in the following patch.

virttest.qemu_devices: Differentiate between qemu and autotest bus type

qemu doesn't differentiate between some of the buses, which are
differentiated in autotest (eg. ahci and ide disks belongs simply
to IDE bus type). In order to be able to distinguish between those
buses we need to add atype (=autotest type) of the bus.

This patch makes this change only for images, where were problems
caused by different qemu/autotest behavior. If this concept prooves
to be right, we can use it to distinguish between various kinds of
USBs in order to reflect the qemu behavior while keeping the autotest
standards.

virttest.qemu_devices: Fix ich9-usb-ehci device creation

There is a hook to create ich9-usb-ehci from multiple devices. Anyway
the device was not plugged into qdev PCI representation thus another
device might use the same address.

qemu_devices still doesn't support x.y PCI address thus plug only
ich9-usb-uhci1 device into this PCI representation into address
0x1d to occupy this slot.
