commit bb0719a80d2f1733d7adcdf326fc91aaf88db167

    msg: Remove redundant #include <sys/msg.h> header
    
    The #include <sys/msg.h> is redundant as we do not use message specific
    types for issuing syscalls to handle msg and shm. Only msgctl requires
    this header.
    
    Build tests:
    ./src/scripts/build-many-glibcs.py glibcs
