fix: chmod +x in genapkovl to fix permissions regardless of git filemode on VM

- genapkovl now explicitly chmod +x init.d/* and usr/local/bin/* after cp
- add bee-net-restart command (short name, no .sh) and /etc/profile.d/bee.sh for PATH
- udhcpc: add & to ensure non-blocking even when DHCP responds immediately
- motd: short commands without paths
