Tobias Klauser b74bf690dc riscv: Disable KSAN_SANITIZE for vDSO
commit f3d60f2a25 upstream.

We use the generic C VDSO implementations of a handful of clock-related
functions.  When kasan is enabled this results in asan stub calls that
are unlikely to be resolved by userspace, this just disables KASAN
when building the VDSO.

Verified the fix on a kernel with KASAN enabled using vDSO selftests.
