Ján Tomko 92572c3d71 Remove code handling the QEMU_CAPS_DOMID capability
This option is xenner-only (since commit b81a7ece),
and we dropped support for xenner in commit de9be0a.

* For test purposes, we may want to fake emulator's output by providing
* our own script instead of a real emulator. For this to work we need to
* specify a relative path in <emulator/> element, which, however, is not
* allowed by RelaxNG schema for domain XML. To work around it we add an
* extra '/' at the beginning of relative emulator path so that it looks
* like, e.g., "/./qemu.sh" or "/../emulator/qemu.sh" instead of
* "./qemu.sh" or "../emulator/qemu.sh" respectively. The following code
* detects such paths, strips the extra '/' and makes the path absolute.
