Make: Fix configure generated for dist-client

Commit 1ec9b94 broke regeneration of configure for dist-client: it
uses .tarball-version, which exists only in the tarball, not in the
source tree.

Generating the client's autoconf stuff into the source tree is a
questionable idea anyway, as it won't run there.  Generate it while
building the tarball instead.

Bonus: doesn't distribute a useless .dirty-stamp.
