travelmate: update 2.1.0

* vpn support can be disabled (enabled by default), fixes #19107 (see trm_vpn option)
* vpn support can be limited to certain interfaces (see trm_vpnifacelist list option)
* openvpn support works now per instance (same as wireguard today)
* add an auto-login script for tplink-omada hotspots provided by Sebastian Muszynski <basti@linkt.de>
* remove pipefail command, see #19043 for reference
