tests: shell: remove RETURNCODE_SEPARATOR

test files are located via find + a pattern search that looks for
_[0-9].  Previous change makes all test scripts return 0 when the
test case is supposed to pass, so the foo_$retval name is no longer
needed.

Update script to look for all executeables in the 'testcases' directory.
This makes it necessary to make two dump-files non-executeable.
