test_create_snapshot: do not try to copy pg_dynshmem dir (#6796)

Browse Source 
## Problem
`test_create_snapshot` is flaky[0] on CI and fails constantly on macOS,
but with a slightly different error:
```
shutil.Error: [('/Users/bayandin/work/neon/test_output/test_create_snapshot[release-pg15-1-100]/repo/endpoints/ep-1/pgdata/pg_dynshmem', '/Users/bayandin/work/neon/test_output/compatibility_snapshot_pgv15/repo/endpoints/ep-1/pgdata/pg_dynshmem', "[Errno 2] No such file or directory: '/Users/bayandin/work/neon/test_output/test_create_snapshot[release-pg15-1-100]/repo/endpoints/ep-1/pgdata/pg_dynshmem'")]
```
Also (on macOS) `repo/endpoints/ep-1/pgdata/pg_dynshmem` is a symlink
to `/dev/shm/`.
