Revert "ANDROID: module: Add vendor hook"

This reverts commit 4d63efb9.

The hooks android_vh_set_module_permit_before_init and
android_vh_set_module_permit_after_init is not used by any vendor, so
remove it to help with merge issues with future LTS releases.

If this is needed by any real user, it can easily be reverted to add it
back and then the symbol should be added to the abi list at the same
time to prevent it from being removed again later.
