A fake vendor snapshot is a vendor snapshot whose prebuilt binaries and
captured headers are all empty. It's much faster to be built than the
real vendor snapshot, so users can exploit the fake vendor snapshot to
reduce the size of vendor snapshot they need, by installing the fake
snapshot and then inspecting the ninja dependencies.

Vendor snapshot can be captured with "m dist vendor-snapshot". With
vendor snapshot and vndk snapshot, older version of /vendor and newer
version of /system will be able to be built together by setting
BOARD_VNDK_VERSION to past vendor's version.
Only vendor modules under AOSP are to be captured. In detail, modules
under following directories are ignored:
- cts/
- device/
- external/clang/
- external/llvm/
- hardware/, except for:
- interfaces/, libhardware/, libhardware_legacy/, ril/
- vendor/
