SELinux: Remove security_get_policycaps()

Browse Source 
The security_get_policycaps() functions has a couple of bugs in it and it
isn't currently used by any in-tree code, so get rid of it and all of it's
bugginess.

/**
* security_get_policycaps - Query the loaded policy for its capabilities

*
* Description:
* Get an array of the policy capabilities in @values where each entry in
* @values is either true (1) or false (0) depending the policy's support of
* that feature. The policy capabilities are defined by the
* POLICYDB_CAPABILITY_* enums. The size of the array is stored in @len and it
* is up to the caller to free the array in @values. Returns zero on success,
* negative values on failure.
