Absolute runpaths in ELF libraries generated by cabal_package

[thufschmitt]

Quite similar to #1127 , although this issue is triggered in a different context by a different rule, so probably worth a different issue

Describe the bug

cabal_package generates .so files that contain absolute references to the sandbox root in their ELF header

To Reproduce

bazel build //tests/binary-with-prebuilt/...
readelf -d bazel-bin/external/stackage/streaming-0.2.2.0/_install/lib/libHSstreaming-0.2.2.0-ghc8.6.5.so| grep .cache/bazel

On my machine, this gives me

$ readelf -d bazel-bin/external/stackage/streaming-0.2.2.0/_install/lib/libHSstreaming-0.2.2.0-ghc8.6.5.so| grep .cache/bazel     06:43:34

Expected behavior

Empty result: The so file shouldn't keep any reference to the cache directory
