Makefile,meson.build: Add support for Sphinx 3.x

Prior to version 4.0, `sphinx-build` outputs man pages to "8" directory
instead of "man8" (for details, see their GitHub issues 7996 and 9217).
Current solution is to rename "8" to "man8" after documentation build.
That enables successful build and installation, as well as dependency
tracking at build-system level, but not on `sphinx-build` own level
upon which `meson` build relies.
