dhcp: add support for vendor specific DHCP option

This adds support for option 43 (Vendor Specific Information) to
libsystemd-network DHCP code. The option carries an opaque object of n
octets, interpreted by vendor-specific code on the clients and
servers.

[@zonque: adopted to new unhexmem() API]
