Also sort `crt-static` in `--print target-features` output

I didn't find `crt-static` at first (for `x86_64-unknown-linux-gnu`),
because it was put at the bottom the large and otherwise sorted list.

Fully sort the list before we print it.

Note that `llvm_target_features` starts out sorted and does not need to
be sorted an extra time.
