procd: fix default timeout for reload trigger actions

Default trigger action timeout was added to procd.sh in commit f88e3a4c
(procd: add default timeout for reload trigger actions)
However, the timeout value was not placed under the correct JSON-script
array nesting level and thus did not apply.

To fix this and make the timeout actually apply to the reload triggers,
we place it in the correct scope, that is the per-trigger array.
