rsync: upgraded package to upstream

Upgraded net-misc/rsync to version 3.2.5 on amd64, arm64.
cros_portage_upgrade fails to upgrade the package due to EAPI=8.
Manually upgraded the package and changed EAPI to 7 and changed python
version as well. Since latest rsync enabled pedantic-errors, compilation
complains that snprintf is redefined. Added a patch to fix the
compilation error.

BUG=b/242291532
TEST=presubmit
RELEASE_NOTE=Upgraded net-misc/rsync package to 3.2.5 and fixed
CVE-2022-29154.
