tests: ensure programs are built before testing

programs may not be built due to missing system dependencies,
or any program can be excluded at configure time with
--enable-no-install-program.  So ensure we're not testing the
system versions in these cases.

* init.cfg (print_ver_): Call require_built_ first.
* tests/misc/tty-eof.pl: Skip programs not built.
* tests/Coreutils.pm (run_tests): Likewise.
* tests/misc/ls-misc.pl: Use 'env test' rather than abs path.
* tests/misc/test-diag.pl: Likewise.
* tests/local.mk: Adjust include order for dependencies.
* tests/misc/arch.sh: Remove redundant calls to require_built_.
* tests/misc/chroot-fail.sh: Likewise.
* tests/misc/groups-dash.sh: Likewise.
* tests/misc/groups-version.sh: Likewise.
* tests/misc/stdbuf.sh: Likewise.
* tests/cp/acl.sh: Remove problematic call to print_ver_ [gs]etfacl.
* tests/mv/acl.sh: Likewise.
* cfg.mk (sc_env_test_dependencies): A new syntax check to enforce
specifying dependencies with print_ver_ for programs
specified through the env command.
* du/bigtime.sh: Add new print_ver_ dependencies.
* du/max-depth.sh: Likewise.
* dd/ascii.sh: Likewise.
* tests/ls/capability.sh: Likewise.
* tests/ls/root-rel-symlink-color.sh: Likewise.
* tests/misc/chroot-fail.sh: Likewise.
* tests/misc/readlink-fp-loop.sh: Likewise.
* tests/misc/sort-debug-keys.sh: Likewise.
* tests/readlink/can-e.sh: Likewise.
* tests/readlink/can-f.sh: Likewise.
* tests/readlink/can-m.sh: Likewise.
* tests/tail-2/inotify-race.sh: Likewise.
* tests/tail-2/inotify-race2.sh: Likewise.
* tests/touch/no-create-missing.sh: Likewise.
* tests/touch/no-dereference.sh: Likewise.
* tests/misc/printenv.sh: Tweak to avoid syntax check trigger.
* tests/misc/help-version.sh: Likewise.
* tests/misc/yes.sh: Likewise.
* tests/misc/printf-quote.sh: Use previously unused $prog.
* configure.ac (EXTRA_MANS): Add $gl_no_install_prog to the list
so that check-x-vs-1 syntax check is satisfied.
