unix: replace "mksysctl_openbsd.pl" script with a Go program

Port mksysctl_openbsd.pl Perl script to mksysctl_openbsd.go.
mkall.sh script is modified to run mksysctl_openbsd.go. Running
mkall.sh does not generate any git diff besides the command
name in comments of generated files. Any missing build tag is
also added in generated files.

Fixes golang/go#27779
