tests: Add ui/attributes/unix_sigpipe/unix_sigpipe-str-list.rs

Which is a variant of [`unix_sigpipe-list.rs`][1] but where a string is
used instead of an identifier. This makes it more similar to the proper
form `#[unix_sigpipe = "sig_dfl"]` and thus more likely to be written by
users by mistake. Also rename the first test to be more in line with the
terminology of [The Reference][2].
