syscall: Add call gate for get_environ_ptr

Browse Source 
Now that the environment strings are stored as an array of strings,
they can be passed from the application via char **environ, which
is really defined as a function call to get_environ_ptr().

This works as is for flat build, but protected mode and kernel mode
require a call gate, which is added here.
