Fix web-wireshark docker build broken by xpra 6.5 release

Browse Source 
Replace the `xpra=6.4*` version clamp on the apt-get install command
line with APT pinning via /etc/apt/preferences.d/pin-xpra.

The previous specifier stopped resolving once xpra 6.5 was released:
the xpra metapackage was pinned to 6.4 while its sub-packages
(xpra-client, xpra-server, xpra-codecs, ...) were unconstrained and
defaulted to 6.5, so apt could not satisfy the dependency graph and
the "Build Docker images" action failed.

Pinning all xpra* packages at the preferences level constrains the
whole set consistently (xpra-html5 is handled separately since it
follows a different version scheme, locked to v19). Blocking every
other version with priority -1 ensures that, if the pinned version
ever disappears from the repository, apt fails loudly instead of
silently upgrading to the latest release.

Fixes GNS3/gns3-registry#1044
