[PATCH] procfs: Fix process creation time in /proc/pid/stat

[Sergey Bugaev]

This was always showing up as 0, because apparently we need to query
creation_time for the task, not a thread.

Here's a before vs after comparison:

$ cat /proc/self/stat ~/procfs/self/stat
11151 (cat) S 26571 11151 26571 0 0 0 0 0 0 0 1 0 0 0 20 0 2 0 0 154783744 251
