Add a PACKAGECONFIG option for slirp, defaulting to internal. This avoids the presence of libslirp on the host causing qemu to link against that instead breaking reproducibility and usability of the binary on hosts where the library isn't present. We need to add it to PACKAGECONFIG by default since users do expect slirp to be enabled in the wider community. Note: qemu version 4.2.0 doesn't support an "internal" option for enable-slirp, so use "git" instead which uses the same configure code path, avoids host libslirp contamination and forces use of the qemu internal slirp implementation.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
