[Bug 1973283] [NEW] dh with tempdir doesn't install into tempdir

[Kyle Bloom]

Public bug reported:

We are using the following rule while doing builds for Synergy
(https://github.com/symless/synergy-core).

> dh $@ --buildsystem=cmake --builddirectory=build -Pbuild/debian
--parallel

It appears on 22.04, the temporary directory gets ignored at some point
and the project binaries get installed into the source debian directory.

This causes an empty-binary-packages warning and the deb is, in fact,
empty.

Our current workaround is the remove the temporary directory flag.
However, I feel this is still a bug worth reporting.
