Fiona Ebner ebfbf39467 ui/vnc-clipboard: fix inflate_buffer
Commit d921fea338 ("ui/vnc-clipboard: fix infinite loop in
inflate_buffer (CVE-2023-3255)") removed this hunk, but it is still
required, because it can happen that stream.avail_in becomes zero
before coming across a return value of Z_STREAM_END in the loop.

This fixes the host->guest direction of the clipboard with noVNC and
TigerVNC as clients.
