boards/lm3s6965-ek: drop dns client and telnetd from qemu-protected
The protected configuration for lm3s6965-ek partitions flash into
128 KiB for the kernel (kflash) and 128 KiB for user space (uflash).
Recent additions to the kernel and VFS caused kflash to overflow by
288 bytes during the CI arm-ti build (arm-none-eabi-ld: section .data
will not fit in region kflash).
Disable the DNS client library (CONFIG_NETDB_DNSCLIENT) and the Telnet
daemon (CONFIG_NETUTILS_TELNETD). In QEMU, DNS resolution is unused by
the built-in examples, and dropping the resolver library saves ~3 KiB
of code from the kernel image and ~2 KiB from user space, restoring
ample flash headroom. Networking (DHCP, TCP/UDP, ping) and the
ELF/module examples remain fully functional.
