libqos: add pc specific interface

Create an operations structure so that the libqos interface can be
architecture agnostic, and create a pc-specific interface to functions
like qtest_boot.

Move the libqos object in the Makefile from being ahci-test only to
being linked with all tests that utilize the libqos features.
