x86: add kmod-acpi-button and kmod-button-hotplug to default packages

Since r40909 openwrt can automatically shutdown when you press the
power button or try to shutdown a kvm virtual machine.
When booting a recent CC-rc2 or trunk image, it doesn't work,
as two kernel modules are missing.

Add these two kernel modules to the default packages, so users
don't need to install them manually.
