Bug 10925: fix LDAP auth failing if DEBUG is enabled

To reproduce:
1/ Edit your apache virtual host and set the DEBUG environment variable
(SetEnv DEBUG 1).
2/ Try to login with an ldap user
3/ You will be redirected to the 500 error page.
The Koha logs contains:
malformed header from script. Bad header=------------------------------: mainpage.pl

The hashdump routine directly prints to STDOUT (!) and breaks the
headers.
It appears Net::LDAP::?->dump does the same thing.

Maybe we can kill C4::Utils after getting rid of this
