patch 9.1.0696: installing runtime files fails when using SHADOWDIR

Problem:  installing runtime files fails when using SHADOWDIR
Solution: revert part of v9.1.0609, since runtime/doc/Makefile's default
          value for VIMPROG does not work if vim was built in a SHADOWDIR.
          (James McCoy)
