ICU 52 local change part 2

ICU 52 local change part 2

Update patches/local1.patch

1. Drop a lot of changes that have been upstreamed since ICU 4.6.x
2. Keep and update exemplar character set for zh*, ja, Indic locales
3. Make timezone names more consistent. Most of the inconsistencies have
   been fixed in the upstream, but there are still some remaining while
   others were fixed after ICU 52.1
4. Minor fixes in other locale data : Date/interval formats, 
   AmPm markers (Indic locales), etc.
