Fix ADM/ADML folder names

ADMX files were not loaded into the GPO editor properly for most
languages because the directory names were bad, e.g. should be 'it-IT'
instead of 'it'. This CL fixes the directory names according to the doc
mentioned in the bug below.

For a few languages the mapping was not clear:
'am', 'fil', 'ml'  - Not in doc; kept the old directory names
'ar' -> 'ar-EG'    - Picked EG as the biggest of the ~15 Arabic countries
'bn' -> 'ms-BN'    - Is this correct? There's no bn-XX in the doc.
'sr' -> 'Cy-sr-SP' - Is this correct? Translations look cyrillic.

BUG=chromium:806577
TEST=Changed components/policy/BUILD.gn to build for all platforms, ran
     ninja -C out/Release -j 2000 policy_templates
     Loaded de-DE into GPO editor on Windows
