```
zig env: remove the json output

The current json output is not very convenient to use from the shell or
a Zig program.
An example using the shell: `zig env | jq -r .lib_dir`.

Remove the json output, and instead use the POSIX shell syntax:
  name="value"

Additionally, when args is not empty, assume each argument is the
environment variable name and print the associated value.
Unrecognized environment variables are ignored.

The new output format has been copied from `go env`, with the difference
that `go env` uses OS specific syntax for windows and plan9.

Define the environment variables in a single place, in order to avoid
possible bugs.

```
