Revert "ANDROID: module: Add vendor hooks"

This reverts commit 60e66878.

The hooks added in it, android_rvh_set_module_core_rw_nx,
android_rvh_set_module_init_rw_nx,
android_rvh_set_module_permit_before_init, and
android_rvh_set_module_permit_after_init, are not used by any vendor
symbol list, so remove them as they are unused.
