x86/kconfig: Enable CONFIG_JUMP_LABEL in the defconfigs

Browse Source 
Enable CONFIG_JUMP_LABEL in the defconfigs, the feature already deals with
GCC not having the asm-goto feature so will not break the build on
older compilers.

Having it enabled generates a faster kernel at very little extra cost
since we already include all the code patching code by having KPROBES
enabled.
