Remove linkerconfig from bionic list.

Note that the list is used to install symlinks to com.android.runtime
and also install "bootstrap" copy in subdir.

We don't need bootstrap/linkerconfig since linker itself provides a
default config for those early processes.

This removes both symlink and bootstrap copy from /system.
