signrom: Rewrite as python script

Now that we have a hard dependency on python anyway, we can replace the
slow shell script to calculate the option ROM checksum with a fast AND
portable python version. Tested both with python 2.7 and 3.1.

kvmvapic: Simplify mp/up_set_tpr

operations and, in case of up_set_tpr, also the ECX push/pop.

optionroms: Silence intermediate file removal

The build process of optionroms spits out an "rm ..." line. Moreover, it
