CHROMIUM: config: Disable BTI on arm64 configs

Having BTI enabled in the kernel causes the android linker to fail
because the vdso has a BTI PLT. We're not using BTI at the moment, so
let's just disable this config for the time being so that various
android apps can be installed and run. Otherwise, the linker barfs and
fails to link programs when they're run, like this:

 WARNING: linker: Warning: "[vdso]" unused DT entry: unknown processor-specific (type 0x70000001 arg 0x0) (ignoring)
