libgo patch committed: Define more structs in syscall package

[Ian Lance Taylor <iant at google dot com>]

This patch to libgo defines more structs in the syscall package,
corresponding to structs defined in the master library.  Bootstrapped
and ran Go testsuite on x86_64-unknown-linux-gnu.  Committed to trunk
and 4.7 branch.
