libelf: Fix double free in __libelf_compress on error path.

In commit 2092865a7e589ff805caa47e69ac9630f34d4f2a
"libelf: {de,}compress: ensure zlib resource cleanup" we added a
call to deflate_cleanup to make sure all resources were freed.
As GCC10 -fanalyzer points out that could cause a double free
of out_buf. Fix by removing the free (out_buf) in __libelf_compress.
