futility: update: Fix build breakagefactory-veyron-7505.B

In old factory branch the compiler, dependency libraries and default
CFLAGS settings were different so we have to hack for FTW.
Also static build (futility_s) needs +static-libs to openssl so let's
disable that.
Also add libzip to tests.

BUG=b:119292628
TEST=emerge-$BOARD vboot_reference; sudo emerge vboot_reference
