rebuild some problematic packages for arm64

node-gyp does not support cross compilation nodejs/node-gyp#829 . prebuild-install properly detects that the current system is arm64 and there are not prebuilts available which causes the node-gyp rebuild to be executed in yarn. However since node-gyp does not support cross compilation is ends up building x86_64 binaries again.

Additionally, the package.json of desktop-trampoline and desktop-notifications call the system install of node-gyp and not the version installed by node. The system install of node-gyp has an issue that causes linking to fail during cross compilation. Calling with npx results in using the node install of node-gyp and avoids this issue.
