Clearer logging on RRDP download timeout

[ties]

As a user, it took me embarrassingly long to realise that this probably was my RP hitting the 60s timeout that we have configured.

config:

# timeout quickly to prevent slow updates
rsync-timeout = 60
rrdp-timeout = 60

log:

For what it's worth, downloads outside routinator seems to easily complete in 60s:
