Switch tzdatacheck to comparing tzdata module file

The old "time zone updates via APK" feature installs time zone data
files in /data. tzdatacheck is run during boot to guard against an
OTA leaving the data in /data older, or in a different format, than the
files that exist elsewhere on device. If such files existed the system
could use old versions of tzdb (and related) data or even end up
unstable.

Soon, the time zone data mainline module will be made "functionally
mandatory" by the removal of most time zone data files from the
runtime module APEX, i.e. the time zone data module cannot be absent,
and the runtime module won't have files to compare against.

This change modifies the command line args for tzdatacheck to reference
the contents of time zone data module instead of the runtime module.
