    mgt: Typo in pthread.h (un)safety net
    
    I was trying to add a safety net to catch pthread usage in MGT code and
    eventually ran into this. Unfortunately, it didn't catch the pthread.h
    inclusion from #4231, because it happened in a header file included
    after mgt.h and in general we should avoid including anything from
    header files, letting C files include everything needed.
    
    This is at least the model for functions like getaddrinfo(): netdb.h
    does not include sys/types.h and sys/socket.h on our behalf.
    
    I'm not sure how to formalize this check beyond a rule to remember
    during code reviews. I said in #4346 that I'd like to add a build-time
    check but it already exists and for now the only way to uphold it is
    discipline.
