lib/lz4: make arrays static const, reduces object code size
Don't populate the read-only arrays dec32table and dec64table on the
stack, instead make them both static const. Makes the object code
smaller by over 10K bytes:
Before:
text data bss dec hex filename
31500 0 0 31500 7b0c lib/lz4/lz4_decompress.o
After:
text data bss dec hex filename
20237 176 0 20413 4fbd lib/lz4/lz4_decompress.o
(gcc version 7.2.0 x86_64)
