[Python][Packaging] Reduce size of macOS and manylinux1 wheels

[asfimport]

The wheels more than tripled in size from 0.12.0 to 0.13.0. I think this is mostly because of LLVM but we should take a closer look to see if the size can be reduced

Wes McKinney / @wesm:
In investigating the wheels I found that something is wrong with the shared library symlinks causing the shared libs to be duplicated. I do not know how much this impacts the final wheel size. Until that issue is fixed at least, I'm not comfortable releasing the project again

This is being reverted in ARROW-5856, as otherwise linking becomes too cumbersome.

There is no need for this to block further releases, lowering Priority to Major.
