[PATCH] [Msan] Fix the if_indextoname.cc test to pass on FreeBSD

[Evgeniy Stepanov]

I don't like it. strncpy zero-initializes this memory whether it's called from inside another interceptor or not.

I'd just change the assert to show that the first strlen()+1 bytes are unpoisoned, without testing the rest of the buffer.

Maybe change the if_indextoname interceptor to poison this area?
