worktree: fix leak in check_clean_worktree()

We allocate a child_env strvec but never free its memory. Instead, let's
just use the strvec that our child_process struct provides, which is
cleaned up automatically when we run the command.

And while we're moving the initialization of the child_process around,
let's switch it to use the official init function (zero-initializing it
works OK, since strvec is happy enough with that, but it sets a bad
example).
