Add MDP exclusion for ThisAssembly class

[josesimoes]

ThisAssembly from Nerdbank.GitVersioning now includes a field initializer. MDP is picking up this and ads it to the stubs and assembly signature.

Need to exclude it from PE parser on all class libs.

This is causing misalignments in assemblies declaration leading to hard faults. Needs fixing ASAP.
