alpm: Use 'pk_backend_job_details_full()' so download size is reported properly

This is needed for download size reporting to work in PK clients which
use the 'download-size' property (introduced in 3741c68) in
'get-details' response. 'download-size' property is available only
when the PK backend uses 'pk_backend_job_details_full()', not
otherwise.
