Incorrect network_security_config.xml with fdroid/gplay withpinning flavors

[af-anssi]

When building any withpinning variant the embedded network_security_config.xml file is not the expected one.

The embedded network_security_config.xml is always the one coming from matrix-sdk-android/src/main/res/xml/network_security_config.xml and not one of vector/src/{fdroid|gplay}/res/xml/network_security_config.xml according to the store dimension.

Using subfolders withpinning in vector/src/fdroid and vector/src/gplay is not working.

After a successful build you can observe the embedded network_security_config.xml in the intermediate folder, for instance in vector/build/intermediates/merged-not-compiled-resources/fdroidTchapWithoutvoipWithpinning/release/xml/ for the variant fdroidTchapWithoutvoipWithpinningRelease.

The official APK published in the Google Play Store also embed the wrong network_security_config.xml.

Using apktool on this APK you can retrieve it under the path res/4u.xml.
