Workaround module test failures by removing the version info from module hashes.
PR12196: The module hash strings are not actually hashing the compiler version
string; the entire version string is being included in the hash. Depending on
the module cache directory name, that can lead to failures where the path
names become too long. As a temporary workaround, just remove the version
string from the hash.
