build: don't use recursive make for tests/ subdirectory

* Makefile.am (SUBDIRS): Remove 'tests'.
(include): The '$(top_srcdir)/tests/local.mk' file.
(check-root): Remove this convenience target, it's no longer needed
now that the "real" check-root target once in 'tests/Makefile' will
land in the top-level makefile.
* configure.ac (AC_CONFIG_FILES): Remove 'tests/Makefile'.
* tests/Makefile.am: Rename ...
* tests/local.mk: ... like this, with a lot of adjustments.
* tests/init.cfg: Move ...
* init.cfg: ... here.  This is necessary, for a limitation of the
gnulib-provided 'tests/init.sh', which unconditionally look for
'init.cfg' in the $(srcdir) directory.
* tests/*/*.sh: Adjust: expect init.sh to be in '$srcdir/tests',
not in '$srcdir', and extend $PATH with './src', not with '../src'.
* tests/Coreutils.pm: Adjust similarly.
* tests/pr/pr-tests.pl ($pfx): Likewise.
