Mark libs as double_loadable

libs(libasyncio libmemtrack libprocinfo libusbhost) have
vendor variants and they are also used by LLNDK(libmediandk)
which means these libs can be double-loaded.

deps:
- libmediandk -> libmedia_jni -> libmtp -> libasyncio
- libmediandk -> libmedia_jni -> libandroid_runtime -> libmemtrack
- libmediandk -> libmedia_jni -> libandroid_runtime -> libdebuggerd_client -> libprocinfo
- libmediandk -> libmedia_jni -> libmtp -> libusbhost
