Subject: [PATCH] gnu: adb: Make compatible with OpenSSL 1.1.

OpenSSL version 1.1 brought some API changes which broke the build here, fix
that by accessing rsa->n (and e) directly, using RSA_get0_key instead.

* gnu/packages/patches/adb-libssl_11-compatibility.patch: New file
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/android.scm (android-platform-system-core)[origin]: Use it.
(adb)[inputs]: Replace openssl-1.0 with openssl.
