tests: migrate test 'printf_escapechars' to the new testsuite

For migrating, merge with the basic structure from 'tests/sample-test',
i.e., source in 'tests/init.sh', call 'print_ver_', "Exit $fail",  etc.
Also remove now-common functions like die() and framework_failure_().

* find/testsuite/test_escapechars.golden: Remove, as the axpected output
is created on the fly by the new test.
* find/testsuite/test_escapechars.sh: Move to ...
* tests/find/printf_escapechars.sh: ... this, and apply the above.
Create the expected output on the fly, and also check for the expected
error diagnostic on stderr.
* find/testsuite/Makefile.am (EXTRA_DIST_GOLDEN): Remove.
(EXTRA_DIST): Remove $(EXTRA_DIST_GOLDEN).
(tests_shell_progs): Remove the reference to this test ...
* tests/local.mk (all_tests): .. and add it here.
