Kir Kolyshkin fdc7ef4071 all: remove ioutil usage from tests ...

This removes the remaining (and trivial) use of deprecated ioutil
package from test files.

Replacements are easy:

	ioutil.ReadAll -> io.ReadAll
	ioutil.ReadDir -> os.ReadDir
	ioutil.ReadFile -> os.ReadFile
	ioutil.WriteFile -> os.WriteFile

While at it, simplify some error reporting.
