Android.mk: Support SYSTEM_EXT* sepolicy

Browse source 
The new variable name reflects its actual usage.

Keep compatibility with BOARD_PLAT_* because it has been a
convention for years.

Amend the README to document the new variables.

Test: `make selinux_policy` with
      `SYSTEM_EXT_{PUBLIC,PRIVATE}_SEPOLICY_DIRS` set,
      observe additions in `$(TARGET_COPY_OUT_SYSTEM_EXT)/etc/selinux`

Alongside vendor sepolicy dirs, OEMs can also amend the public and private
policy of the product and system_ext partitions:
SYSTEM_EXT_PUBLIC_SEPOLICY_DIRS += device/acme/roadrunner-sepolicy/systemext/public
SYSTEM_EXT_PRIVATE_SEPOLICY_DIRS += device/acme/roadrunner-sepolicy/systemext/private
PRODUCT_PUBLIC_SEPOLICY_DIRS += device/acme/roadrunner-sepolicy/product/public
PRODUCT_PRIVATE_SEPOLICY_DIRS += device/acme/roadrunner-sepolicy/product/private
The old BOARD_PLAT_PUBLIC_SEPOLICY_DIR and BOARD_PLAT_PRIVATE_SEPOLICY_DIR
