update_chroot: Don't reinstall binpkgs based on date
The combination of --update, --usepkgonly, and --deep causes emerge to
reinstall all binpkgs that have a newer BUILD_TIME. Since we upload new
prebuilts when the SDK builder runs, this causes a large fraction of the
entire chroot to get reinstalled every couple of days.
What we really want is for changed/updated packages and their
dependencies to be reinstalled, so --deep is still needed. Pass
--rebuilt-binaries=n to avoid reinstalling packages where the only
change is the build timestamp.
BUG=b:218731092
FIXES=b:218731092
TEST=./update_chroot installs 8 packages instead of 485
