main/busybox: fix some tab completions written to stdout

Most tab completions are written to stderr but some were written to stdout
which sometimes lead to output written in the wrong places.

Fixes #16566

+Subject: [PATCH] lineedit: fix some tab completions written to stdout
+
+In fd47f056765 (lineedit: print prompt and editing operations to stderr)
+some output was left printing to stdout. This can causes a race condition
+between stderr and stdout which in some cases leads to output written in
+the wrong places.
+
+Downstream issue: https://gitlab.alpinelinux.org/alpine/aports/-/issues/16566
+Fixes: fd47f056765
