Change libxlMakeDomainCapabilities() to void, since all
checks, which results in returning -1, are, in fact, not
possible.
libxlMakeDomainOSCaps(),
libxlMakeDomainDeviceDiskCaps(),
libxlMakeDomainDeviceGraphicsCaps(),
libxlMakeDomainDeviceVideoCaps(),
libxlMakeDomainDeviceHostdevCaps() also changing to void,
because they are invariant.
Test fillXenCaps() at moment is useless,
so it could be removed or changed in the future.
