rmodule: align ld script with latest x86 ld script 

The x86 linker script added a .textfirst section. In
order to properly link ramstage as a relocatable module
the .textfirst section needs to be included.

Also, the support for code coverage was added by including
the constructor section and symbols. Coverage has not been
tested as I suspect it might not work in a relocatable
environment without some tweaking. However, the section
and symbols are there if needed.
