live_ast: don't set working directory

contrib/scripts/live_ast currently assumes that it is being run from the
top-level directory of the source tree. It creates a script that will
also set the working directory.

This fix avoids the need to set the working directory if the caller sets
LIVE_AST_BASE_DIR instead.

It relies on realpath for that. If realpath is not available, it will
fall back to the original behaviour.
