dload: avoid renaming files downloaded via sync operations
If the server redirects from ${repo}.db to ${repo}.db.tar.gz pacman gets this wrong: It saves to new filename and fails when accessing ${repo}.db. We need the remote filename only when downloading remote files with pacman's -U operation. This introduces a new field 'trust_remote_name' to payload. If set pacman downloads to the filename given by the server. The field trust_remote_name is set in alpm_fetch_pkgurl(). Fixes FS#36791 ([pacman] downloads to wrong filename with redirect).
