ANDROID: gki_defconfig: Make 'saveconfig' check happy

CONFIG_BPF_{JIT,JIT_ALWAYS_ON,SYSCALL} Kconfig entries were moved from
init/Kconfig to their very own file in kernel/bpf/Kconfig during the
latest Mainline release candidate.  This has the unfortunate side-
effect of ending up in slightly different places in 'saveconfig's
resultant .config file.

The upshot is that CI now fails, despite no real change to the config
taking place.  This patch makes CI happy again.
