ethernet: change MTU type to size_t

Modify the type to get this working on 64-bit system.

In phosphor-dbus-interfaces, the type is `size`:
https://github.com/openbmc/phosphor-dbus-interfaces/blob/8a2674b/yaml/xyz/openbmc_project/Network/EthernetInterface.interface.yaml#L26

phoshor-networkd has this correct and no other places use.
https://github.com/openbmc/phosphor-networkd/blob/6f256bc591bec72dd1448522d941874b21145a81/src/ethernet_interface.hpp#L146

Tested:
```
Before:
 curl localhost/redfish/v1/Managers/bmc/EthernetInterfaces/eth0 -s | grep MTU
  "MTUSize": 0,
After:
 curl localhost/redfish/v1/Managers/bmc/EthernetInterfaces/eth0 -s | grep MTU
  "MTUSize": 1500,
```
