SST: VLen Array

[ax3l]

In ADIOS 2.10.2, I see the following compile warning

source/adios2/toolkit/sst/cp/cp_reader.c:141:18: warning: variable length array folded to constant array as an extension [-Wgnu-folding-constant]
  141 |         char Tmp[strlen(SSTMAGICV0)];
      |                  ^~~~~~~~~~~~~~~~~~

cc @eisenhauer ? :)

Actually literally old code. That got fixed a while back, so that code does not appear in master. (We need to do a new release.)
