[release-branch.go1.13] runtime: fix wrong offset when calling ppc64x nanotime syscall
There is a wrong offset when getting the results of a clock_gettime
syscall. Although the syscall will never be called in native ppc64x,
QEMU doesn't implement VDSO, so it will return wrong values.
For #36592
Fixes #38236
