sqlite: do not contaminate dependent libtool-based projects with sqlite dependencies

sqlite is built as a shared library, but libtool nevertheless adds -lz into the
link commands of the dependent projects, which fail to link if they do not
directly depend on libz.  Fix this by clearing dependency_libs in libsqlite3.la.
