[PATCH v1 5/5] ui-system: Use argv for talloc context

[Geoff Levand]

Process instances are no longer allocated using talloc, so use the argv
instance as the talloc context.

Fixes runtime errors like these when using the --start-daemon option:

  talloc_chunk_from_ptr: Assertion `0 && "Bad talloc magic value - unknown value"' failed.
