Add fs_config_files_vendor and fs_config_dirs_vendor to deps

These are required deps of the phony .mk module
`fs_config_*_nonsystem`, which is added to PRODUCT_PACKAGES in
`build/make/target/product/base_vendor.mk`

Test: verified that these files are present in the autogenerated vendor
partition module
