[gn] Support dots in CMake paths in the sync script

[phosek]

Summary

Some file paths use dots to pick up sources from parent directories.

Drive-by.

My mistake, disregard.

Looks good, but I don't understand the CMake change.

compiler-rt/lib/sanitizer_common/CMakeLists.txt

Are you intentionally removing this?

After the sync_source_lists_from_cmake.py change, this one is being flagged, but there are other headers like this one for other architectures, e.g. sanitizer_common_interceptors_vfork_x86_64.inc.S, none of which are listed in the CMake file, so I figured it's better to remove this one to make this file self-consistent.

Ping?

Ok, looks like this file is included somewhere and removing it here shouldn't change the build. Maybe .S.inc would be a better name :)
