feat(stonedb): To support unspecify the location of 3rd libs(#12). (#382)

If you DO NOT specify the boost, rocksdb and marisa installed path, stonedb will think
these libs were installed at system directories, such as `/usr/local`, etc. Therefore, now,
stonedb will use these system path as run-path when do compiling.
