Update the "host" bionic code tzdata lookup logic 

The "if defined(__ANDROID__)" else branch is there to support
bionic when running on host environments.

The code now checks the
${ANDROID_RUNTIME_ROOT}/etc/tz/tzdata path as well.

This is similar to the current on-device expectations.

Eventually, we may remove the /system / ANDROID_ROOT cases.
