tvhdhomerun: Add ISDB to type check in tvhdhomerun_device_create

This commit adds support for ISDB in the type check of the tvhdhomerun_device_create function in tvhdhomerun.c.
This allows the function to handle ISDB type devices, which previously would have been changed to a DVB device on startup every time despite overrides.
