Release-ready candidate for upstream 1.4.4+dfsg
- New upstream version 1.4.4+dfsg
- Refresh patches
- Call Salsa CI with variable DB_BUILD_PARAM: '-v1.1.2-1', since this is the oldest version in active repositories
- Add Rules-Requires-Root: binary-targets to debian/control to comply with current DPM
- Bump Standards-Version to 4.4.1, changes noted above
- Update symbols file for libzstd1
- Call dh_makeshlibs with -V 'libzstd1 (>= 1.4.4)', since this version introduced new public symbols
- Add an entry in debian/source/lintian-overrides to prevent libzstd1's Section entry from triggering binary-control-field-duplicates-source, since this field is necessary for the build
