Fix unchecked return value from strdup

Browse Source 
The pg_dump compression was using strdup() instead of pg_strdup()
and failed to check the returned pointer for out-of-memory before
dereferencing it. Fix by using pg_strdup() instead which probably
was the intention here in the original patch.

Backpatch to v16 where pg_dump compression was introduced.
