sparse-checkout: use extern for global variables

When the core.sparseCheckoutCone config setting was added in 879321eb0b ("sparse-checkout: add 'cone' mode" 2019-11-21), the variables storing the config values for core.sparseCheckout and core.sparseCheckoutCone were rearranged in cache.h, but in doing so the "extern" keyword was dropped. While we are tending to drop the "extern" keyword for function declarations, it is still necessary for global variables used across multiple *.c files. The impact of not having the extern keyword may be unpredictable. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
