Revert "Symbols for libs in APEXes are available"

This reverts commit 769e50b3.

Reason for revert: Likely causing build failure on aosp_x86_64-eng in aosp_master:

"build/make/core/base_rules.mk:271: error: art/build/apex: MODULE.TARGET.SHARED_LIBRARIES.com.android.runtime.host.libart-compiler already defined by art/build/apex."
