Remove platform availability from internal libs that make up
libdexfile_support_static.

init and debuggerd no longer depends on libunwindstack with DEX support
(https://r.android.com/1149620), and with the fix for NOTICE targets on
static libs (https://r.android.com/1274763) it is not needed for
simpleperf_ndk either.

Test: Build & boot
Test:
  $ m libdexfile libartbase libartpalette
  $ find out/target/product/*/system -name libdexfile.so -o -name libartbase.so -o -name libartpalette.so
