utils: Do not raise exceptions in delete-file-recursively.
This makes it so that delete-file-recursively honors its docstring, which says it should "report but ignore errors". Fixes <https://issues.guix.gnu.org/43366>. * guix/build/utils.scm (warn-on-error): New syntax. (delete-file-recursively): Use it to catch exceptions and print warning messages.
