The standard library perror() function provides a convenient way to print an error message based on the current errno but this doesn't play nicely with KTAP output. Provide a helper which does an equivalent thing in a KTAP compatible format.

nolibc doesn't have a strerror() and adding the table of strings required doesn't seem like a good fit for what it's trying to do so when we're using that only print the errno.

Oh, interesting... what environment ends up without strerror()?
