support for arm64-v8a

[vdaele]

Some feedback when adding support for arm64-v8a.
I first modified build-all-arch.sh and set archs=(armeabi-v7a x86 arm64-v8a)

In setenv-android-mod.sh, I had to replace randlib with ranlib (a typo I guess?)

In android-openssl.pri I would suggest to use
$$PWD/../../android-openssl-qt/prebuilt/$$ANDROID_TARGET_ARCH/libcrypto.so

Note also that Qt5.13 will be packaged with OpenSSL1.1 afaik

thanks
next week I'll switch to Qt 5.13 and openSSL 1.1
I'll rely on https://github.com/KDAB/android_openssl

BTW: AFAIK 5.13 is not packaged with openSSL for Android

Thanks for pointing me to the KDAB repo (although I was quite happy with yours :-) )
My last sentence should probably be rephrased to "Note also that the QtNetwork in 5.13 expects an OpenSSL 1.1 API" (see also https://bugreports.qt.io/browse/QTBUG-76290)

YEP ;-)
