Merge #12308: contrib: Add support for out-of-tree builds in gen-manpages.sh

526e28220a contrib: Add support for out-of-tree builds in gen-manpages.sh (Wladimir J. van der Laan)

Pull request description:

  This adds support for setting the environment variable `BUILDDIR` to point to executables that are outside the source directory.

  E.g. to invoke the tool when the build is in $PWD/build:

  ```bash
  BUILDDIR=$PWD/build contrib/devtools/gen-manpages.sh
  ```

  This avoids having to manually copy the generated manpages after they end up in the build instead of source path, when setting TOPDIR instead.
