[PATCH] docs: writing_tests: Make docs correspond the latest changes

[Ivan Orlov <ivan.orlov0322@gmail.com>]

We should store test object files list in the `libsbi-objs-y` Makefile
variable, not in `libsbitests-objs-y`. Update the documentation
correspondingly.

Since we don't use the `console_dev` static variable directly in the
`sbi_console_test` unit test anymore, remove the paragraph which says
that we do.

 You don't have to compile the `sbi_string_test.o` separately, because the
 test code will be included into the `sbi_string` object file.
