man: Fix swapped stdin/stdout for redirection operators

The Redirections section incorrectly claimed that <& replaces stdout
and >& replaces stdin. Swapped them to make it read correctly.

Ref:

Both errors were followed by extra text that looked like remains of a
mostly-deleted sentence. Removed those.
