efi_selftest: ReinstallProtocolInterface test

Browse source 
Test ReinstallProtocolInterface() more rigorously.

Replacing the sole installed protocol interface must not result in deleting
the handle and creating a new one.

Check which interface is actually installed before and after
ReinstallProtocolInterface().
