lei_query: fix relative path handling on --stdin

Since --stdin could be waiting on user keyboard input or
something else slow, we handle it in the event loop.  That
means other commands can change the working directory of
lei-daemon while a query is being trickled to us via stdin.

Rearranging query handling internals to delay opening the
--output destination in commit 26e0fe73de93f451 meant
another command could throw off our --output pathname if
it is relative.

Fixes: 26e0fe73de93f451 ("lei_query: rearrange internals to capture query early")
