syscall: Use vsyscall for syscall.Gettimeofday and .Time on linux amd64.
Regenerate zsyscall_linux_*.go files with recent changes to mksyscall.sh. Add socketpair to syscall_linux_amd64.go; for some reason it was in the generated file but not in the source file. R=rsc, r2 CC=golang-dev https://golang.org/cl/2190044
