We have the same problem with p4.  I fixed it in t98* in
23bd0c9 (git p4 test: use real_path to resolve p4 client
symlinks, 2012-06-27), but maybe an exported
TRASH_DIRECTORY_REAL_PATH might be generally useful.

There's a portable test helper that does this already:

    path=$(test-path-utils real_path "$path")
