Update fix-duplicate-tcp-ports patch to preserve existing TCP ports when
DrbdRscData is recreated during toggle-disk operations. Without this,
removeLayerData() frees ports and ensureStackDataExists() may allocate
different ones, causing port mismatches between controller and satellites
if the satellite misses the update.

Also add dh_strip_nondeterminism override in Dockerfile to fix build
failures on some JAR files.
