Unzip bin and libs from otatools.zip for build_mixed

For build_mixed, only "bin" and "lib64" are required from the
otatools.zip.
Instead of unzipping all files, unzip only the required files from
the otatools.zip.

Also update the usage for -t option.

Bug: 112732863
Test: build_mixed -v 9 -m modify_system_img.sh -p vbmeta.img \
                  -t otatools.zip system product dist checkvintf
