Use env variables to select custom qemu-img and qemu-system-x86_64
binaries. This is needed to test versus latest Qemu versions from
Github.
If env variable QEMU_BIN is not present then the defaults for test
are system-wide installed packages.
This partly reverts changes done in patch:
5502294d76
which removed possibility to run with custom Qemu binaries.
