slirp: Handle whole 127.0.0.0/8 network as local addresses.
Changes so translation of remote address to the host's ip address in the virtual network happens for all addresses in the 127.0.0.0/8 network, not just 127.0.0.1. This fixes so that hostfwd bound to addresses such as 127.0.0.2 works. Signed-off-by: Anders Waldenborg <anders@0x63.nu> Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
