package/systemd: fix "Timed out waiting for device /dev/console."

Browse Source 
Buildroot built with systemd fails to open a login prompt on the
serial port when /dev/console is specified as BR2_TARGET_GENERIC_GETTY_PORT
(which is its default value):

systemd[1]: dev-console.device: Job dev-console.device/start timed out.
systemd[1]: Timed out waiting for device /dev/console.
systemd[1]: Dependency failed for Serial Getty on console.
systemd[1]: serial-getty@console.service: Job serial-getty@console.service/start failed with result 'dependency'.
systemd[1]: dev-console.device: Job dev-console.device/start failed with result 'timeout'.
systemd[1]: Reached target Login Prompts.
systemd[1]: Reached target Multi-User System.

According to this issue on Github [1], serial-getty@.service should
not be instantiated on /dev/console, console-getty@.service should
be used instead. This stems from the fact that there should be no
dependency on /dev/console.

# systemd needs getty.service for VTs and serial-getty.service for serial ttys
# note that console-getty.service should be used on /dev/console as it should not have dependencies
# also patch the file to use the correct baud-rate, the default baudrate is 115200 so look for that
