Fix missing NOTICE targets for static libs that aren't available to

Browse Source 
platform.

The NOTICE file generation depends on the NOTICE targets for all static
library dependencies. If such a dependency didn't have
//apex_available:platform it didn't get any AndroidMk entry and hence
no NOTICE target via soong_cc_prebuilt.mk. If it was then depended upon
by a binary or library that is accessible to platform, the NOTICE
dependency failed.

Normally such a dependency is invalid, but there are corner cases where
binaries go neither into platform nor any APEX module, and they can
legitimately have such dependencies (cf. b/152241137).

With this CL requests to skip installation of such a static libraries
are ignored so that they get AndroidMk entries, which will always have
LOCAL_UNINSTALLABLE_MODULE set.

Test: "m simpleperf_ndk" with https://r.android.com/1273016, which
  removes //apex_available:platform from libs that simpleperf_ndk
  depends on statically.
