Bug#1007731: php-fpdf: Unused build dependencies on libldap2-dev and libgdbm-dev

[Ryan Tandy]

I confirm the libldap2-dev dependency is unused. I rebuilt php-fpdf with 
it removed and libldap2-dev purged, and the resulting .deb was 
bit-identical.

The dependencies on po-debconf and quilt also look suspect to me, as the 
package has no debconf templates and no patches.
