compile busybox cp with reflink support

Given that:
(a) Alpine supports BTRFS
(b) Alpine uses busybox as its default coreutils

It would be useful if that enabled access to functionality useful for BTRFS (namely —reflink).

Comments in the busybox code (https://git.busybox.net/busybox/tree/coreutils/cp.c) seem to suggest there is reflink support if you choose to compile it:

//config:config FEATURE_CP_REFLINK
//config:   bool "Enable --reflink[=auto]"
//config:   default y
//config:   depends on FEATURE_CP_LONG_OPTIONS
