Since D129389 (and downstream PR https://github.com/apple/llvm-project/pull/4965), the dependency scanner is responsible for generating full command-lines, including the modules paths. This patch removes the flag that was making this an opt-in behavior in clang-scan-deps.

Sharing the FileManager across implicit module builds currently leaks
paths looked up in an importer into the built module itself. This can
cause non-deterministic results across scans. It is especially bad for
modules since the path can be saved into the pcm file itself, leading to
stateful behaviour if the cache is shared.
This should not impact the number of real filesystem accesses in the
scanner, since it is already caching in the
DependencyScanningWorkerFilesystem.
Note: this change does not affect whether or not the FileManager is
shared across TUs in the scanner, which is a separate issue.
