Allow to negotiate the packet command and responses to
whatever values the EC can support.
Set the buffer size including the necessary V3 header.
If the EC run v3 protocol with large packet support, but the kernel
does not have v3 support (3.10), we can not support sending or
receiving large commands.
Be aware that on 3.10, commands like ectool console will fail if
the EC wants to send command larger than the kernel can handle.
Copied kernel_version_ge from libusb-1.0.19/libusb/os/linux_usbfs.c.

BRANCH=none
TEST=Build a special firmware to exchange 300 bytes.
Check ectool console works with the righ size.
Check that ectool is calling uname.
Check on Nyan_big: without change, "ectool version" crashes kernel. With
changes, "ectool version" works.
In conseuqence, it reverts commit be0bd9b835,
"ectool: Do not increase buffer size after probe max size from ec"
