rsync: remove upstream's rebuild logic

Upstream some well intended but broken logic to reimplement the rebuild
functionality of automake. However this isn't out-of-tree safe and quite basic,
which means if it ever does execute (say, configure.ac or aclocal.m4 is touched)
then the build fails.

As we delete ${B} and re-run autoreconf on every build this is redundant, so
just delete it all.

+Remove the Makefile rules to reinvoke autoconf, they're not out-of-tree safe and
+generally overcomplicated, and we ensure that autoreconf is invoked if required.
