testsuite: fix syntax in Wstringop-overflow-59.c

Fix quoting issues, escaping, and dg directive types.

There were two issues here:
1) The incorrect quoting in an earlier dg-message was covering up that the
syntax in the next part was wrong;
2) Fix dg-warning -> dg-message to correctly pick up the notes. Once 1) was
fixed, this was exposed.

With this, I get:
```
+PASS: gcc.dg/Wstringop-overflow-59.c note (test for warnings, line 192)
+PASS: gcc.dg/Wstringop-overflow-59.c note (test for warnings, line 193)
```

gcc/testsuite/ChangeLog:
	PR middle-end/92936

	* gcc.dg/Wstringop-overflow-59.c: Fix dg-* syntax.
