Replace the entire environment of processes launched from this
launcher with the given 'environ' variable.
Typically you will build this variable by using g_listenv() to copy
the process 'environ' and using the functions g_environ_setenv(),
g_environ_unsetenv(), etc.
Pass an empty array to set an empty environment. Pass NULL to inherit the
parent process’ environment. As of GLib 2.54, the parent process’ environment
will be copied when Subprocess.launcherSetEnviron is called.
Previously, it was copied when the subprocess was executed. This means the
copied environment may now be modified (using Subprocess.launcherSetenv,
etc.) before launching the subprocess.
On UNIX, all strings in this array can be arbitrary byte strings.
On Windows, they should be in UTF-8.
