Context: Add more uniqueness to temp directory names.

Browse Source 
- If a single thread attempted to establish multiple package kit
  contexts, it would fail due to a collision between their respective
  temporary directories. As such, use both the thread ID and
  system_time() as a random elements in the directory name to ensure
  this doesn't occur.
