[buildidtool] Write an empty stamp for missing build ID

When the binary doesn't have a build ID, write an empty stamp file
rather than skipping the write altogether. This is easier to handle
in the build system when we don't need to special case the missing
stamp file. This also handles the case when the binary had a build
ID before but no longer has it which is broken in the current case
as the tool leaves the old stamp behind.
