tests: migrate 'execdir-fd-leak' to the new testsuite

* find/testsuite/sv-34976-execdir-fd-leak.sh: Move to ...
* tests/find/execdir-fd-leak.sh: ... this, and apply the above.
Simplify, and make more robust.
* find/testsuite/Makefile.am (tests_shell_progs): Remove the reference
to this test ...
* tests/local.mk (all_tests): .. and add it here.
