[samsung-n5110][samsung-jflte] dhcpcd not working

On the Samsung Galaxy Note 8.0, dhcpcd does not seem to work:

dhcpcd exited

The busybox dhcp client (udcpc) works without any problems. However, as pmOS (postmarketos-base to be precise) depends on networkmanager/dhcpcd now, the busybox ifup function no longer uses udhcpc but dhcpcd. Therefore, afaik, there is no easy way to use udhcpc instead of dhcpcd.
