We re-use an existing define BUSYBOX_INTERNAL_SHADOW_PASSWORDS that was used to do some musl-related tweaks to the Busybox configuration around shadow password functions, and extend it to also do the utmp/wtmp tweaks. In the process, we rename the define to BUSYBOX_MUSL_TWEAKS. Note that BUSYBOX_KCONFIG_FIXUP_CMDS continues to call BUSYBOX_INTERNAL_SHADOW_PASSWORDS because there is another definition of this macro under other conditions.
