don't use mutable keyword for sys::env data members

* oct-env.h, oct-env.cc (sys::env::m_current_directory,
sys::env::m_prog_name, sys::env::m_prog_invocation_name,
sys::env::m_user_name, sys::env::m_host_name): Don't declare data
members as mutable.
(sys::env::do_polite_directory_format, sys::env::do_getcwd,
sys::env::do_get_home_directory,
