partly revert 92a9b7780c6e13a4da3b12794342edbc4c09ef51 for ICU < 49

Re-enable build with ICU 4.6 and 4.8
ICU versions prior to 49 don't know Conditional_Japanese_Starter and
Hebrew_Letter

Also, the change in i18npool/CustomTarget_breakiterator.mk

- -e "s#\[:LineBreak = Close_Punctuation:\]#\[& \[:LineBreak = Close_Parenthesis:\]\]#" \

with i18npool/source/breakiterator/data/line.txt

-$CL = [:LineBreak = Close_Punctuation:] ;
+$CL = [:LineBreak = Close_Parenthesis:];

did not produce equivalent results. Instead use

$CP = [:LineBreak =  Close_Parenthesis:];
$CL = [[:LineBreak =  Close_Punctuation:] $CP];
