Subject: preload-index: use git_env_bool() not getenv() for customization
X-Git-Tag: v2.20.0-rc0~162^2~4

preload-index: use git_env_bool() not getenv() for customization

GIT_FORCE_PRELOAD_TEST is only checked for presence by using getenv().
Use git_env_bool() instead so that GIT_FORCE_PRELOAD_TEST=false can
work as expected.
