Revert "Add the cwg to the prebuilt module cache path." (#2160)

This reverts commit 5298b418eec4129351888f41cb7c3bfc90161e22.

This commit was mistakenly committed. PR was opened in #1730, but it was
closed and moved to #1761. I didn't notice this and created another PR
in #1980.

This change was causing 100+ failures in runtime cxxmodules nightlies.

We want to have **proper** PrebuildModulesPaths which information were
extracted from LD_LIBRARY_PATH and DYLD_LIBRARY_PATH, not a random ".".

Because of this commit, we were trying to autoload libraries generated
by roottest on-demand (for example "./h1analysisTreeReader_C.so") This
is not an intentional behavior, these autogenerated libraries are
already loaded by roottest and what we want to do is to load **proper**
libraries like libHist.so instead.
