Phase2 packages buildbot fails - timeout with rsync.openwrt.org since 5 days ago

[Hannu Nyman]

Phase2 packages buildbot currently fails almost all buils due to timeout with 
rsync.openwrt.org.
(some packages architectures are now 5 days without successfull builds.)

https://buildbot.openwrt.org/main/packages/#/grid

Example:

rsync -4 -v --timeout=120 -a 
'rsync.openwrt.org::downloads/snapshots/targets/bcm27xx/bcm2711/openwrt-sdk-*.tar.*' 
sdk.archive
  in dir /builder/aarch64_cortex-a72/build (timeout 1200 secs)
