lib: rsa: consider CONFIG_SPL_RSA

CONFIG_SPL_RSA is meant to control if lib/rsa/* is used for SPL. Adjust
lib/Makefile to consider this setting.

This was correctly setup with commit 51c14cd128f4 ("verified-boot: Minimal
support for booting U-Boot proper from SPL") and got lost with commit
089df18bfe9d ("lib: move hash CONFIG options to Kconfig").

Fixes: 089df18bfe9d ("lib: move hash CONFIG options to Kconfig")
