Add new test for octal and letter escapes in -printf format.

* find/testsuite/test_escapechars.golden: Expected output file.
* find/testsuite/Makefile.am (EXTRA_DIST_GOLDEN): New variable;
distribute test_escapechars.golden.
* find/testsuite/test_escapechars.sh: New test.
* find/testsuite/Makefile.am (test_shell_progs): New variable,
where we keep the list of shell script tests.  Move existing
examples from TESTS and add test_escapechars.sh.
* find/testsuite/Makefile.am (TESTS): Refer to test_shell_progs.
* cfg.mk: allow trailing blanks and space-tab sequences in
find/testsuite/test_escapechars.golden.
