[druntime-test]: exceptions: Skip spurious memoryerror

These tests seem to fail with a shared druntime (depending on arch as well), and work with a static one. CI fails with a static druntime though. A gdb backtrace with a shared druntime: ``` Reading symbols from ./a... (No debugging symbols found in ./a) (gdb) r Starting program: /root/build/a [Thread debugging using libthread_db enabled] Using host libthread_db library "/usr/lib64/libthread_db.so.1".
