[oe] [meta-oe][PATCH v2] rocksdb: Turn off Werror to fix build failure due to GCC9 checks

[zhe.he at windriver.com]

From: He Zhe <zhe.he at windriver.com>

GCC9 introduce stricter checks, deprecated-copy and pessimizing-move, while
rocksdb uses -Werror and causes the following build error.

db/version_edit.h:178:33: error: implicitly-declared 'constexpr rocksdb::FileDescriptor::FileDescriptor(const rocksdb::FileDescriptor&)' is deprecated [-Werror=deprecated-copy]

utilities/persistent_cache/persistent_cache_util.h:51:23: error: moving a local object in a return statement prevents copy elision [-Werror=pessimizing-move]

Signed-off-by: He Zhe <zhe.he at windriver.com>

v2: As suggested, turn off Werror instead of the two specifc check options
