Yanqin Jin 30edf1874c Change buckifier to support parameterized dependencies (#5648)
Summary:
Users may desire to specify extra dependencies via buck. This PR allows users to pass additional dependencies as a JSON object so that the buckifier script can generate TARGETS file with desired extra dependencies.

Test plan (on dev server)
```
$python buckifier/buckify_rocksdb.py '{"fake": {"extra_deps": [":test_dep", "//fakes/module:mock1"], "extra_compiler_flags": ["-DROCKSDB_LITE", "-Os"]}}'
Generating TARGETS
Extra dependencies:
{'': {'extra_compiler_flags': [], 'extra_deps': []}, 'test_dep1': {'extra_compiler_flags': ['-O2', '-DROCKSDB_LITE'], 'extra_deps': [':fake', '//dep1/mock']}}
Generated TARGETS Summary:
- 5 libs
- 0 binarys
- 296 tests
```
Verify the TARGETS file.
