[PATCH v2 05/16] Use msgget syscall for Linux implementation

Changes from previous version:

  - Use __ASSUME_SYSVIPC_SYSCALL instead of __NR_syscall to issue the
    wired syscall or the ipc one.


This patch add a direct call to msgget syscall if it is supported by
kernel features.

hecked on x86_64, i686, powerpc64le, aarch64, and armhf.
