This implements the interface from luaposix:
http://luaposix.github.io/luaposix/modules/posix.sys.utsname.html
It's a bit nicer than using io.popen() or similar to run uname(1).

| 65 | Why do we compile these modules (lfs, posix.*, etc.) into flua rather than having them be regular modules? This means that they are automatically imported into the global namespace. Though, that actually doesn't appear to work properly for posix.*: markj@nuc> /usr/libexec/flua

Seems fine to me; we can move it out to a module with the rest of lposix later.

| 65 | lfs was initially compiled in because I needed it to be available in bootstrap flua for makesyscalls processing, and bootstrap flua doesn't support modules. The others I noted to bapt a little while ago should probably start moving into proper modules so that other non-flua things using base liblua could also use them (e.g., if we redo config(8) with lua, it'll almost certainly be its own C frontend that uses liblua to interpret config files and whatnot) | |

| 62 | To provide an example for what I have in mind in the future, I'd for example create a freebsd.lib.uname and implement it in lua using posix.sys.utsname and freebsd.sys.sysctl. The latter is needed for some uname(1) flags that are useful, like uname -p. | |
| 65 | Sorry for the maybe dumb question: why doesn't bootstrap flua support modules, assuming that we can compile said modules together with flua? | |
