configs/pc_x86_64_{bios, efi}_defconfig: unbreak after qemu bump to linux-4.11

The pc_x86_64 defconfigs reuse the linux configuration from qemu_x86_64, but
they weren't adjusted when this was updated to use linux-4.11 in 28d97609b25
(configs/qemu: bump to the latest kernel version), breaking the build.

Fix it by also moving them to linux-4.11.x.
