extract db files with dbonly
Some database files (install, mtree, and changelog) are extracted directly from the package, but DBONLY was skipping extraction altogether, causing those files to be missing after the transaction. Fixes #52052 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org> (cherry picked from commit 2c4511bdbe3599713811e54edbbd60e51d66ce3e)
