Add support for Android Emacs #231

Describe the bug This is a feature request: Add support for Android emacs. See pull request #230

Add support for pdf-tools-install in Android Emacs using Termux. The dependencies for android in autobuild can not be installed in pdf-tools-install, they have to be installed manually in Termux. But the dependencies are checked when running autobuild.

pdf-tools-install successfully installs epdfinfo in Android Emacs. One can then view pdf files.

The shebang in autobuild does not work in Termux, I therefore had to create a separate script "autobuild.android" that in turn executes autobuild. The problem with the shebang is that "env" in Termux is not located at "/usr/bin/env".

pdf-tools/Makefile does currently not work in Android Emacs, but it is not needed for running pdf-tools-install. Fixing this will have to be done in a separate pull request, if deemed necessary. Reason: There is yet no consensus for how to implement a command line emacs, to be run in batch mode, in Android Emacs.

I have successfully run "make test" in Ubuntu, in the repo feature branch. Running "make server-test" in the master branch fails, so I have not tested this in the feature branch.
