MT#61568 debian: Remove redundant debhelper install fragment file

The upstream build system is already installing the files into the
expected destination, so there is no need to list them here again.

In fact, duplicating the installation is causing build failures when
building as non-root, such as:

  cp: cannot create regular file 'debian/…': Permission denied

As a side effect this change, stops installing *.t test suite files
in the binary package, as should have been the case initially.
