Subject: [PATCH] kitty: always export `KITTY_SHELL_INTEGRATION`

This ensures that `KITTY_SHELL_INTEGRATION` is manually set to the
user's `shellIntegration.mode`. This is necessary because sometimes
the variable is not set in subshells or splits.
`shellIntegration.mode` is also now ensured to always contain `no-rc`.
