configs/qemu_x86_64_defconfig: remove kernel options that need openssl/libelf

The ORC unwinder requires libelf to be available on the host, so use
the frame pointer unwinder instead. Using the frame pointer unwinder
is probably good enough in our default Qemu configurations.

Wireless support ends up enabling CONFIG_SYSTEM_TRUSTED_KEYRING, which
requires openssl to be available on the host, so disable wireless
support, which isn't needed in Qemu.
