unix: make TimevalToNsec available everywhere

It wasn't in linux/arm.

Tested with:

$ for x in $(go tool dist list ) ; do \
     export GOOS=$(echo $x | cut -d/ -f1); \
     export GOARCH=$(echo $x | cut -d/ -f2); \
     echo "$GOOS; $GOARCH"; go install  .; done

... which all pass, except openbsd/arm which is still broken exactly
how it was broken previously.

Fixes golang/go#14643
