Bug description:
  === Begin SRU Template ===
  [Impact]
  The key change is that the user agent string as of Zesty and Artful now
  contains the contents of /proc/uptime. In aggregate, this gives us
  important performance data to detect improvements and regressions in
  Ubuntu boot times.

  [Test Case]
  Launch a privileged container with:

  1. lxc launch ubuntu-daily:xenial -c security.privileged=true x1-priv
  2. lxc exec x1-priv -- apt update && apt -y install pollen

  Run a local pollen server and have the pollinate (client) connect with
  that via:

  3. lxc exec x1-priv -- pollinate -r --insecure -s https://localhost

  Then check in /var/log/syslog for the client user-agent string.  On
  systems without the updated pollinate client, the USER_AGENT value
  does not include uptime:

  root@x1-priv:~# grep pollen /var/log/syslog | grep -c uptime
  0
  root@x1-priv:~# 

  After upgrading to the newer client, uptime is now present in the
  pollen entries:

  root@x1-priv:~# grep pollen /var/log/syslog | grep -c uptime
  2
  root@x1-priv:~# 

  The two changes are:
  a.) the defaults file /etc/default/pollinate file was sourced twice during
  execution. That was unlikely to cause issue, but the cleanup removed
  unnecessary duplication.

  b.) uptime is read from /proc/cpuinfo and added to the USER_AGENT
  variable that is fed to curl.

  [Regression Potential]
  The script runs with 'set -e', and reads from /proc/uptime with:
     read up idle < /proc/uptime

  That means that the 'pollinate' script will exit failure if either:
  a.) /proc/uptime did not exist (possibly proc not mounted)
  b.) a read error occurred.

  These scenarios seem unlikely, especially in Ubuntu environments.
  The upstream code should check to at least check the readability of
  /proc/uptime first.  I've filed bug 1708461 to address that issue
  and submitted a merge proposal for a fix.

  [Other Info]
  The reading of up/idle from uptime was originally added under bug 1638552.
