obit r438

Remove patches that are now part of upstream Obit since revision 438.
ObitView no longer requires autoconf to be run and the test scripts
take the test data directory as argument.
obit: Enable parallel builds

Add missing build dependencies in Obit, ObitTalk and ObitView to enable
parallel (make -jN) builds. Without these explicit dependencies targets
such as executables and libraries are built before the object files
that they depend on, as these high-level targets are built in parallel.
