Install libdw-dev so dpkg-checkbuilddeps passes (amd64 + arm64)

Browse Source 
The kernel's generated debian/control lists libdw-dev:native as an
unconditional Build-Depends, so dpkg-buildpackage aborts via
dpkg-checkbuilddeps before the build starts -- regardless of .config.
Disabling BTF/pahole never satisfied this check.

libdw-dev is just the elfutils libdw headers and does not make pahole
run; dwarves stays absent since DEBUG_INFO_BTF is disabled.
