tree-wide: rewrite ioutil functions to their replacements
The ioutil package has been deprecated in Go 1.16 [1]. This CL removes
all our own users of that package and rewrites them to use their
replacements in the os package. I initially wanted to do this with a
gofix but because all replacements were signature-compatible I just
did it with a few string replaces and then ran goimports to fix up the
imports.
I intentionally didn't rewrite the patches as that would require a
different process and is IMO of less value.
