dhcpcd: security bump to version 6.11.0

Fixes CVE-2014-7913: The print_option function in dhcp-common.c in dhcpcd
through 6.10.2 misinterprets the return value of the snprintf function, which
allows remote DHCP servers to execute arbitrary code or cause a denial of
service (memory corruption) via a crafted message.
