package/dhcp: add host-gawk optional dependency

On hosts where gawk is not available, it is not possible to build the
package with server option (BR2_PACKAGE_DHCP_SERVER).
The build goes through without errors but the binaries are not created
and installed. The reason is that autotools cannot find gawk.
