    GSubprocess test: Add PATH to the envtable that is passed to child
    
    envp in spawn() functions is the *whole* environment table
    for the child process. Including PATH. Thus, unless PATH is explicitly
    put into that table, the process will be spawned without PATH.
    Since on Windows binaries are found via PATH instead of LD_LIBRARY_PATH
    or whatever, almost no program (unless installed in WINDIR, maybe)
    can run without a PATH. Certainly not test programs - meson
    adds bld subdirs to the PATH to make sure that test programs
    use uninstalled glib at runtime.
    So make sure that PATH is passed along.
