Subject: [PATCH v2 13/14] selftests/nolibc: tinyconfig: add extra common options

The original kernel tinyconfig target has already enabled some common
options, but they are not enough to enable boot and print.

    $ find kernel/ arch/*/ -name "tiny*.config"
    kernel/configs/tiny-base.config
    kernel/configs/tiny.config
    arch/x86/configs/tiny.config

To enable qemu boot and console print, additional kernel config options
are required, include the common parts and the architecture specific
parts.

Here adds minimal extra common parts for all architectures:

* for initrd: CONFIG_BLK_DEV_INITRD
* for init executable: CONFIG_BINFMT_ELF
* for test result print: CONFIG_PRINTK, CONFIG_TTY
