policycoreutils: sepolicy: rename policy global variable

Variable policy is both a global variable and a parameter to some
functions in policycoreutils/sepolicy/search.c.  This makes the building
fail when using -Wshadow -Werror compilation flags.

Fix this by renaming the global variable global_policy.  This does not
change the API of the Python module.
