Convert the hostname to all-lowercase in fix_hostname() so that

the implementation matches the comments.  (Note: The current virtual
hosting code does case-insensitive host matching, so this fix is useful
mostly to help ensure that custom modules and any future vhosting code
don't get tripped up by case-sensitivity issues.)
