[runtime] When shadow-copying assemblies, use the io portability function to find...

This is necessary in situations when managed code pases case-insenstive file name and the
file on disk uses different case. stat(2) would return an error in such situation and, in effect,
the stat structure would get invalid/random values in its fields.
