fix open_port with many unset env vars
The erlang:open_port spawn and spawn_executable directives can include
an {env, Env} directive to set up environment variables for the
spawned process. Variables can be unset with {"NameOfVariable",false}.
A bug in ert/emulator/sys/unix/sys.c could cause unset variables
to not be unset. This would typically happen if there where more
variables to be unset than there where already set variables in the
destination evironment.
Fix this problem for unix and add a new regression test for it to
the port test suite. Windows does not seem to have the same problem.
