In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf
return values, leading to a buffer overflow in later code.

Notes

Author	Note
mdeslaur	possible better approach would be to disable tcp_emu completely https://gitlab.freedesktop.org/slirp/libslirp/commit/07c2a44b67e219ac14207f7a1b33704e1312cf91
