build-sys: move slirp as git submodule project

The slirp project is now hosted on freedesktop at:
https://gitlab.freedesktop.org/slirp.

The libslirp source was extracted from qemu/slirp filtered through
clang-format (available in project tree). The qemu slirp directory can
be swapped by a git submodule.
