dtv-scan-tables: rename file to have only ASCII characters

Since the bump of dtv-scan-tables to version
ceb11833b35f05813b1f0397a60e0f3b99430aab in commit
b1c8794d8ac0eb3895d13ae91d8e912ec469a105, one file contains non-ASCII
characters, which causes encoding issues tvheadend. Since no other
file in the dtv-scan-tables code base contains files with non-ASCII
characters (despite having files named after cities in various
countries that definitely do have non-ASCII characters), we rename
this file so that it is named with only ASCII characters.

This fixes the build of tvheadend, which was failing when the host
Python interpreter was python3, due to a file name encoding issue.

Fixes:
