lineedit: use stdout for shell history builtin

Commit fd47f0567 (lineedit: print prompt and editing operations
to stderr) changed various print statements to output to stderr.
The change in show_history() caused the shell history builtin to
send its output to stderr.

Revert that part of the commit.
