Description of change

When I build the addon on the OpenHarmony operating system, I encounter errors related to linker parameters.

For example, this is the error log I encountered when building bufferutil.

# npm install bufferutil

The cause of this error is that the addon.gypi in node-gyp is not adapted to the OpenHarmony. This PR adds adaptation for this platform.
