Enforce no nonexistent modules in PRODUCT_PACKAGES for sdk builds

Bug: 5430740
- Remove nonexistent names in PRODUCT_PACKAGES.
- Push down bluetooth-health, hostapd and wpa_supplicant.conf to
generic_no_telephony.mk and large_emu_hw.mk because they are not needed
by sdk builds.
- Remove core.mk from generic_armv5.mk and generic_x86.mk because they
  already inherit from generic.mk.
