sys/targets: add OS/Arch name consts

We use strings to identify OS/Arch.
These strings are duplicated throughout the code base massively.
golangci-lint points to possiblity of typos and duplication.
We already had to define these names in pkg/csource
and disable checking for prog package. A future change triggers
such warnings in another package.

Add OS/Arch name consts to sys/targets so that they can be used
to refer to OS/Arch. Use the consts everywhere.
