Fix failing build by not propagating deployment target to deps (#2103)

Summary:
Pull Request resolved: https://github.com/facebook/flipper/pull/2103

Local builds break if the deploy target of deps isn't new enough. It seems that the project podfile is not respected in this regard, as reported here: https://stackoverflow.com/a/37289688/1983583. Will see if there is a better way to fix this.
