re PR go/81451 (missing futex check - libgo/runtime/thread-linux.c:12:0 futex.h:13:12: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘long’)

	PR go/81451
    runtime: inline runtime_osinit
    
    We had two identical copies of runtime_osinit. They set runtime_ncpu,
    a variable that is no longer used. Removing that leaves us with two lines.
    Inline those two lines in the two places the function was called.
    
    This fixes GCC PR 81451.
