debian: Make the package creation work on debian squeeze (stable)

the dh_autoreconf application did not honor the sourcedirectory
option back then. Override the target and call autoreconf from
the right directory.
The libdbi development package is called libdbi0-dev. Use this name
for Debian stable but it should work for Ubuntu as well.
