Permit IPv6 Address Router Advertisement values to be changed

The current IPv6 Address Router Advertisement value written to the
configuration file is always 'false'. This allows DBus to update the
configuration file with either boolean value.

Tested:
Used dbus-send to modify the IPv6AcceptRA property.  Confirmed the
/etc/systemd/network/00-bmc-ethx.network file updated.
