android-tools: export libsparse/libbase/liblog headers and libs to sysroot

Export libsparse, libbase, and liblog headers and libraries to the sysroot.
Currently, these are often internal to the build.
Reorganise header installation to ${includedir}/sparse to match the expected
include paths for e2fsprogs contrib tools.
