Update snappy to 1.1.10

[timsueberkrueb]

snappy 1.1.10 includes "compilation fixes for various environments". In particular, it fixes compilation on older systems like Debian Buster, which previously failed due to snappy relying on the =@ccz assembly constraint, which is not supported in clang 7 which ships with Debian Buster:

  running: "c++" "-O3" "-ffunction-sections" "-fdata-sections" "-fPIC" "-m64" "-I" "snappy/" "-I" "." "-Wall" "-std=c++11" "-DNDEBUG=1" "-o" "/__w/qdrant/qdrant/target/x86_64-unknown-linux-gnu/release/build/librocksdb-sys-906afbc25bf7847d/out/snappy/snappy-c.o" "-c" "snappy/snappy-c.cc"
  exit status: 0
  cargo:warning=snappy/snappy.cc:1033:36: error: invalid output constraint '=@ccz' in asm
  cargo:warning=      : [tag_type] "+r"(tag_type), "=@ccz"(is_literal));
  cargo:warning=                                   ^
  cargo:warning=1 error generated.
  exit status: 1

Updating snappy to 1.1.10 is sufficient to make the compilation succeed on Debian Buster.
