Avi Kivity 0ed178a01e build: disable the -fextend-variable-liveness clang option ...

In clang 21, the -fextend-variable-liveness option was made
default [1] with -Og. It helps reduce "optimized out" problems while
debugging.

However, it conflicts [2] with coroutines.

To prevent problems during the upgrade to Clang 21, disable the option.

Closes scylladb/scylladb#26573
