Move java/incrementing-version-code to AndroidManifest.xml.in

* admin/admin.el (admin-android-version-code-regexp): New
variable.
(set-version): Modify AndroidManifest.xml.in instead.

* java/AndroidManifest.xml.in (Version-code): Define version
code.

* java/incrementing-version-code: Delete file.

(cherry picked from commit 121371a706491fde8c06d95b13c16703d53f6fa3)
