Revert "common: spl_fit: Default to IH_OS_U_BOOT if FIT_IMAGE_TINY enabled"

Commit cf8dcc5d02c3 ("common: spl_fit: Default to IH_OS_U_BOOT if
FIT_IMAGE_TINY enabled") is not correct, it will append fdt to each loadable
image. Actually when using TINY FIT, the first loadable image is thought as
u-boot and already have fdt appended.
