Suppress Clang warning on adding an integer to a string, like:

tst-iconv-sticky-input-error.c:125:42: error: adding 'int' to a string does not append to the string [-Werror,-Wstring-plus-int]
  125 |                 expected_output = "ABXY" + skip;
      |                                   ~~~~~~~^~~~~~
tst-iconv-sticky-input-error.c:125:42: note: use array indexing to silence this warning
  125 |                 expected_output = "ABXY" + skip;
      |                                          ^
      |                                   &      [     ]
