test/blobfs: rocksdb building error with gcc9

Browse Source 
There's a small error when building rocksdb in blobfs db_bench
with gcc9:
"strncpy output truncated before terminating nul copying as many
bytes from a string as its length [-Werror=stringop-truncation]"

It's not a real bug for in the code "strncpy" truncates the null
terminator but set it later, which has been reported here:
https://github.com/facebook/rocksdb/issues/4017
Just adding "-Wno-error=stringop-truncation" to silent the compiler.
