Summary:
Declare Jemalloc non-standard APIs as weak symbols, so that if Jemalloc is linked with the binary, these symbols will be replaced by Jemalloc's, otherwise they will be nullptr. This is similar to how folly detect jemalloc, but we assume the main program use jemalloc as long as jemalloc is linked: https://github.com/facebook/folly/blob/master/folly/memory/Malloc.h#L147

Summary:
Don't enable ROCKSDB_JEMALLOC unless the build mode is opt and default
allocator is jemalloc. In dev mode, this is causing compile/link errors such as -

Summary:
Slightly changes the format of generated BUCK files for Facebook consumption. Generated targets end up looking like this:
```
cpp_library(
    name = "rocksdb_tools_lib",
    srcs = [
        "tools/db_bench_tool.cc",
        "tools/trace_analyzer_tool.cc",
        "util/testutil.cc",
    ],
    auto_headers = AutoHeaders.RECURSIVE_GLOB,
    arch_preprocessor_flags = rocksdb_arch_preprocessor_flags,
    compiler_flags = rocksdb_compiler_flags,
    preprocessor_flags = rocksdb_preprocessor_flags,
    deps = [":rocksdb_lib"],
    external_deps = rocksdb_external_deps,
)
```
Instead of
```
cpp_library(
    name = "rocksdb_tools_lib",
    srcs = [
        "tools/db_bench_tool.cc",
        "tools/trace_analyzer_tool.cc",

Summary:
Set the macro if default allocator is jemalloc. It doesn't handle the case when allocator is specified, e.g.
```
cpp_binary(
    name="xxx"
    allocator="jemalloc", # or "malloc" or something else
    deps=["//rocksdb:rocksdb"],

Summary:
We're moving away from `import`. The equivalent internal construct that
gets the directory from `fbcode/` is `package_name()`. This is a
Skylark friendly wrapper around [`get_base_path`].

The additional whitespace change is from running `python ./buckifier/buckify_rocksdb.py`.
