Include tcmalloc's config before tcmalloc.h

Certain things in tcmalloc.h depend on tcmalloc's config.h file,
for instance whether struct mallinfo exist or not. Depending
on how the functions are used, it may or may not work correctly
without including config.h, but to be safe, always include it.

This was an issue in jumbo builds if base/process/memory_linux.cc
and base/allocator/allocator_shim_default_dispatch_to_tcmalloc.cc
were compiled in the same translation unit. The wrong includes from
memory_linux.cc caused the other file to fail to compile.
