project-lakitu: disable VDSO on ARM by default

ChromeOS only enable VDSO when it compiles 32-bit ARM while
on guest OS, we are running 64-bit ARM. Disable VDSO by
default to resolve the regression created by merging  5.10.89

BUG=b/213228511
TEST=presubmit
RELEASE_NOTE=Won't enable VDSO on ARM by default
