setup tftp_remote_ip and tftp_filename environment variable for next usage

Problem: no way determinate real filename and remote ip after tftp transfer 1) serverip can be different from real tftp remote ip 2) filename same determined automatically

Example

=> setenv bootfile 192.168.100.80:/ && pxe get ... => printenv tftp_filename tftp_remote_ip serverip tftp_filename=/pxelinux.cfg/default-arm-meson tftp_remote_ip=192.168.100.80 serverip=192.168.100.1
