Subject: [PATCH 3/3] ci.yml: test cross-compiling for Android

From: Eric Biggers <ebiggers@...gle.com>

Add jobs that cross-compile e2fsprogs for Android using the Android NDK.
These use the autotools-based build system, so they're a bit different
from the actual Android builds, but they should still be useful.
