Make qemuCmdFlags available in qemudDomainAttachDevice()

qemudDomainChangeEjectableMedia() currently extracts the qemu command
line flags, but other device attaching code might need it, so move
the qemudExtractVersionInfo() call up a frame.

* src/qemu_driver.c: move the qemudExtractVersionInfo() call from
  qemudDomainChangeEjectableMedia() to qemudDomainAttachDevice()
