erts: Remove use of VALGRIND_PRINTF_XML

which only existed in a patched version of valgrind (by pan)
no longer used.

Instead we use standard VALGRIND_PRINTF which will end up like this
if valgrind log format is XML and valgrind version >= 3.9:

<clientmsg>
  <tid>7</tid>
  <threadname>3_scheduler</threadname>
  <text>Test case #20 ei_encode_SUITE:test_ei_encode_long/1
  </text>
</clientmsg>

Note the extra trailing whitespace that may occure before </text>.
