[AIX] Remove --as-needed passing into aix linker

[jasonliu]

Summary

AIX does not support --as-needed linker options. Remove that option from aix linker when -lunwind is needed.
For unwinder library, nothing special is needed because by default aix linker has the as-needed effect for library that's an archive (which is the case for libunwind on AIX).

LGTM, thanks!
