netifd: relax check in dhcp proto handler

Checking whether /sbin/udhcpc is a symbolic link breaks using the
DHCP proto handler inside procd-ujail where bind-mounts are used for
the resolved link. Check whether /sbin/udhcpc is executable instead
to allow using the proto handler for DHCP-provisioned containers.
