libalpm: simplify sync db lastupdate
Legacy code is hitting the trash here. Remove unnecessary _alpm_time2string time storage abstraction in favor of just writing the time_t value to the disk. The only drawback is that everyone's sync DBs will have to be updated at least once so that the lastupdate values are stored right. :) Signed-off-by: Dan McGee <dan@archlinux.org>
