Replace '@flow strict(-local)' with '@flow' in .android.js files

Summary:
Flow doesn't check .android.js files yet anyway.

I'm going to be adding suppressions in a followup diff. It would be nice to not have >1k suppressions saying that we can't do certain things in `flow strict` when we don't even typecheck with regular `flow` just yet

I ran these commands to produce this diff:
`find . -name '*.android.js' -exec sed -i 's/flow strict-local/flow/g' {} +`
`find . -name '*.android.js' -exec sed -i 's/flow strict/flow/g' {} +`

Followed https://unix.stackexchange.com/questions/112023/how-can-i-replace-a-string-in-a-files to do it.

The controller you requested could not be found.
