add helper method to generate same crc32 results as php and boost::crc_32_type

Summary:
This revision adds a helper method in folly/Checksum.h, that returns the same crc32 value as php's built-in implementationa and boost::crc_32_type.

folly's default implementation only differs from the final xor (with 0xFFFFFFFF for boost and php, 0 for folly), which is added here.
