Dan Willemsen 2be559488d Exclude ndk stubs from notice file list
There are many references to ndk stub libraries in the third party
notices:

out/soong/ndk/platforms/android-10/arch-arm/usr/lib/libc.so
out/soong/ndk/platforms/android-10/arch-arm/usr/lib/liblog.so
...

These are just stub libraries, and aren't distributed on the device. The
real versions of these libraries will be distributed on the device, and
already have the license information.

So let Soong set LOCAL_NO_NOTICE_FILE to prevent these from appearing.

Bug: 36867708
Test: Diff aosp_arm's system/etc/NOTICE.html.gz file before/after
