Fix security problem on PermissionMonitor#hasPermission

PermissionMonitor#hasPermission only checks permssions that app
requested but it doesn't check whether the permission can be
granted to this app. If requested permission doens't be granted
to app, this method still returns that app has this permission.
Then PermissionMonitor will pass this info to netd that means
this app still can use network even restricted network without
granted privileged permission like CONNECTIVITY_INTERNAL or
CONNECTIVITY_USE_RESTRICTED_NETWORKS.
