libalpm/sync.c: don't duplicate packages for the sync->data field.
Packages put in the sync->data field were always duplicated with pkg_dup, and then freed, This is not needed. Killing this duplication of packages made the memory usage during base reinstall go from 10.4 MB to 8.1 MB. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
