rm: with -I, prompt before deleting a write protected file

This regression was introduced in commit v6.7-71-g0928c24

* src/rm.c (main): Make the -I option behave like --interactive=once.
* tests/rm/interactive-once.sh: Add cases for single and multiple files.
* NEWS: Mention the bug fix.
Fixes http://bugs.gnu.org/9308

   tail --retry -f now waits for the files specified to appear.  Before, tail
   would immediately exit when such a file is inaccessible during the initial
   open.
