netlink: specs: binder: replace underscores with dashes in names

The usage of underscores is no longer allowed for the 'name' format in
the yaml spec. Instead, dashes should be used. This fixes the build
issue reported by Thorsten that showed up on linux-next.

Note this change has no impact on C code.
