Marc Horowitz 05cb7ce1c5 Make ios-install-third-party.sh more robust
Summary:
See https://github.com/facebook/react-native/issues/14423

This adds checks after download that each file is present, and has the
correct sha1 hash.  If not, it will retry several times, and fail if
it can't successfully download the file.  If a file is downloaded, the
unpack and command will run, even if the third-party dir already
exists.  The diagnostics printed in the event of failure are improved.

This should be self-healing for anybody who has a bad ~/.rncache
directory.  The checksum will fail, and the files will be
redownloaded.
