libgo patch committed: Don't copy semt into runtime.inc

[Ian Lance Taylor]

PR 81449 reports a libgo problem with the definition semt in
runtime.inc on some systems. Since the C code in libgo/runtime doesn't
need semt, just don't copy it into runtime.inc.  Bootstrapped and ran
Go testsuite on x86_64-pc-linux-gnu.  Committed to mainline.
