Mark libminijail as VNDK

This commit marks libminijail as a VNDK library so that the vendor
variant can be installed into /system/lib[64]/vndk instead of
/vendor/lib[64].

This library was not a VNDK library in Android O because its Android.mk
hasn't been converted to Android.bp at the time.  Thus, we were asking
vendors to use libminijail_vendor instead and omx implementation has to
use libavservice_minijail_vendor.  Since Android.mk has been converted
to Android.bp, it would be great to mark this library as VNDK library so
that libminijail can be updated through system-only OTAs.

Bug: 63866913
Test: Build sailfish and libminijail.so should be installed into
/system/lib[64]/vndk/libminijail.so instead of
/vendor/lib[64]/libminijail.so.

+# If you don't need to do a full clean build but would like to touch
+# a file or delete some intermediate files, add a clean step to the end
+# of the list.  These steps will only be run once, if they haven't been
+# run before.
+#
+# E.g.:
+#     $(call add-clean-step, touch -c external/sqlite/sqlite3.h)
+#     $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates)
+#
+# Always use "touch -c" and "rm -f" or "rm -rf" to gracefully deal with
+# files that are missing or have been moved.
+#
+# Use $(PRODUCT_OUT) to get to the "out/target/product/blah/" directory.
+# Use $(OUT_DIR) to refer to the "out" directory.
+#
+# If you need to re-do something that's already mentioned, just copy
+# the command and add it to the bottom of the list.  E.g., if a change
+# that you made last week required touching a file and a change you
+# made today requires touching the same file, just copy the old
+# touch step and add it to the end of the list.
+#
+# ************************************************
+# NEWER CLEAN STEPS MUST BE AT THE END OF THE LIST

+
+# For example:
+#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/APPS/AndroidTests_intermediates)
+#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/JAVA_LIBRARIES/core_intermediates)
+#$(call add-clean-step, find $(OUT_DIR) -type f -name "IGTalkSession*" -exec rm -f {} \;)
