systemd: remove default.network

Yocto now installs a file 80-wired.network[1] which contains the
same information as the 'default.network' except that it also
enables IPv6 dhcp.  Remove the 'default.network' in our bbappend
since it is redundant.

Any configuration created by phosphor-networkd is created as
00-bmc-*.network, which will take precedence lexigraphically over
this 80-wired.network default.
