river: make spawn command take only one argument
Currently the spawn command takes any number of arguments and naively
joins them together with spaces before passing them as the single
argument of `/bin/sh -c`. This however produces unexpected results as
soon as shell quoting gets involved in the arguments passed to spawn.
For example, running
riverctl spawn foo "bar baz"
will execute `/bin/sh -c "foo bar baz"`, unexpectedly splitting bar and
baz into separate arguments. To avoid this confusion, make the spawn
command take only a single argument, forcing the user to quote properly
to spawn multi-argument commands.
