Allow plugins to add pkg-config dependencies to rocksdb.pc (#9198) 

Summary:
This patch fixes an issue that occur when dependencies of plugins are not
installed to the same prefix as librocksdb. Because plugin dependencies are
declared in the `Libs` field of rocksdb.pc, programs that link against
librocksdb with `pkg-config --libs rocksdb` will link with `-L` flag for the
path of librocksdb only. This patch allows plugin dependencies to be declared in
the `Requires` field of rocksdb.pc, so that pkg-config will correctly provide
`-L` flags for dependencies of plugins that are installed in other locations.
