Subject: diffcore-pickaxe: support case insensitive match on non-ascii

diffcore-pickaxe: support case insensitive match on non-ascii

Similar to the "grep -F -i" case, we can't use kws on icase search
outside ascii range, so we quote the string and pass it to regcomp as
a basic regexp and let regex engine deal with case sensitivity.

The new test is put in t7812 instead of t4209-log-pickaxe because
lib-gettext.sh might cause problems elsewhere, probably.
