Add a test for shadowing/overlapping packages with Cabal

# SETUP=../Setup
SETUP=../Setup -v0
# This test is for overlapping/shadowing packages with Cabal. We
# 1. install p-1.0 to the global DB
# 2. install q-1.0 (depending on p-1.0) to a temporary DB
# 3. install a differnet p-1.0 to the temp DB
# 4. attempt to configure and buidl r, which depends on p-1.0 and q-1.0
# step 4 will elicit a warning from Cabal's configure step that the
# packages are inconsistent, and will cause an error from GHC.
# Currently the error message from GHC is swallowed by Cabal.

Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
