tailscale: fix fw_mode env by using append_param

The previous commit 09c14817 introduced TS_NO_LOGS_NO_SUPPORT but
used procd_set_param for a subsequent environment variable. This
overwrote the previous env setting, causing fw_mode to be missed.

Switch to procd_append_param to ensure all environment variables are
properly passed to the process.
