make_chroot: drop git/curl/openssl manual updating

This code is necessary when openssl is a cros-workon package, but we
migrated away from that a while ago.  Dropping this logic speeds up
chroot creation and simplifies the code.

BUG=chromium:342199
TEST=`cbuildbot chromiumos-sdk` passes
TEST=creating a new chroot works
