Remove duplicated get_upgrades function, use sysupgrade instead. 

The alpm_get_upgrades was exactly the same as find_replacements +
_alpm_sync_sysupgrade, except that it automatically made the eventual
replacements, without asking the user : Replace %s with %s/%s? [Y/n]

The replace question, asked in find_replacements. can now be skipped by
using a NULL trans argument, so that we get the same behavior as with
alpm_get_upgrades.

So alpm_db_get_upgrades() can now be replaced by
alpm_sync_sysupgrade(db_local, syncdbs).
