Skip PresetCompressionDict test for lite
Summary: This test relies on "rocksdb.num-files-at-levelN" property that isn't implemented in rocksdb lite. So we will compile it only for non-lite builds. Test Plan: $ make -j40 check 'OPT=-g -DROCKSDB_LITE' Reviewers: sdong, IslamAbdelRahman Reviewed By: IslamAbdelRahman Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D57387
