tests: Add '--duplicate-sources' to libgem5 SST build

Browse Source 
Unfortunately the building of SST (in "ext/sst") depends on generated
header files. Therefore it adds the build directory to the include path.
For this to work the libgem5.so must be build with
"--duplicate-sources".

**Note:** `--without-tcmalloc` is required to avoid a conflict with SST's malloc.
`--duplicate-sources` is required as the compilation of SST depends on sources to be present in the "build" directory.
