Make reproducible builds from master branch

[likern]

Description

Every time I try to build react-native-reanimated npm package from master it fails.

I use script createNPMPackage.sh, other ways didn't work. Being able to build complete npm package from master is very important, otherwise I can't test patches against master branch and can't verify they are working.

...

* What went wrong:
Execution failed for task ':buildReanimated'.

It would be very good to have CI tests that check source code from master at least is building for iOS and Android.

It seems like you're using some wrong version of folly.

Does run-android work for you? I would recommend to try to build for device/emulator using Android studio - what's how I used to build it.

Script createNPMPackage.sh calls android tasks through gradle command line, I think there should be no difference whether I call tasks from command line or through Android Studio.

I've tried to call assembleDebug using Android Studio and see the same error.
Folly version is picked up and downloaded by downloadFolly task

Download https://github.com/facebook/folly/archive/v2020.01.13.00.tar.gz
> Task :downloadFolly
> Task :prepareFolly

def FOLLY_VERSION = reactProperties.getProperty("FOLLY_VERSION")
...
task downloadFolly(dependsOn: createNativeDepsDirectories, type: Download) {
    src("https://github.com/facebook/folly/archive/v${FOLLY_VERSION}.tar.gz")
    onlyIfNewer(true)
    overwrite(false)
    dest(new File(downloadsDir, "folly-${FOLLY_VERSION}.tar.gz"))
}

which takes FOLLY_VERSION from ./node_modules/react-native/ReactAndroid/gradle.properties

FOLLY_VERSION=2020.01.13.00

Is used the latest React Native version - now it is 0.63.2, released 4 days ago.

After successfully generating react-native-reanimated-2.0.0-alpha.4.tgz I still see "Unsatisfied Link Error" for reanimated.so when try to use this reanimated package as dependency (using yarn add file://...).

The same problem have with running Example app.
