Remove unnecessary code

The master copy from system/core/bootstat/bootstat.rc is already copied
and invoked from /system/etc/init, and we only need to do car specific
tasks within this file.

Bug: 128544877

Test: build and flash locally, then check backtrace from logcat, there
shouldn't be any crashes from bootstat process.
