linux-user: Check sscanf return value in open_net_route()
Coverity warns (CID 1390634) that open_net_route() is not
checking the return value from sscanf(), which means that
it might then use values that aren't initialized.
Errors here should in general not happen since we're passing
an assumed-good /proc/net/route from the host kernel, but
if we do fail to parse a line then just skip it in the output
we pass to the guest.

linux-user: add new netlink types
Add QEMU_IFLA_MIN_MTU, QEMU_IFLA_MAX_MTU (from linux v4.19)
QEMU_IFLA_BRPORT_ISOLATED (from linux v4.18) and
QEMU_IFLA_BRPORT_BACKUP_PORT (from linux v4.19).
These new types fix this error flow with sudo:
...
Unknown host QEMU_IFLA type: 50
Unknown host QEMU_IFLA type: 51
Unknown QEMU_IFLA_BRPORT type 33
