Win32: unify environment case-sensitivity

Browse Source 
The environment on Windows is case-insensitive. Some environment functions
(such as unsetenv and make_augmented_environ) have always used case-
sensitive comparisons instead, while others (getenv, putenv, sorting in
spawn*) were case-insensitive.

Prevent potential inconsistencies by using case-insensitive comparison in
lookup_env (used by putenv, unsetenv and make_augmented_environ).
