vrunner: fix file descriptor close syntax for coproc

The syntax {SOCAT[0]}<&- is invalid - curly braces are for allocating
new file descriptors, not referencing existing ones. Use eval with
${SOCAT[0]} to properly close the coproc file descriptors.

Fixes: "SOCAT[0]: ambiguous redirect" error when using daemon mode.
