revert: use pre-release versioning and set version to 1.1.1-0.11.6

Description

The go command cannot recognize the build metadata(+) tag, this causes a problem in wasmd where the version check of libwasmvm cannot be done.

• https://github.com/Finschia/wasmd/blob/1eb1bbdfbb07d19152acc7f0143bb53386c54fc8/x/wasm/module.go#L271-L284
• https://github.com/Finschia/wasmd/blob/1eb1bbdfbb07d19152acc7f0143bb53386c54fc8/x/wasm/module_test.go#L590-L606

So I reverted to the previous pre-release versioning of wasmvm.

Set version to v1.1.1-0.11.6.

Have you tried the libwasmvm.dylib in #129 to test wasmd?

It has not even to do with the cause of this problem.
Thanks for the suggestion.
