File fix-build-icu59.patch of Package libqt4

From: Fabian Vogt <fvogt@suse.com>
Subject: Fix build with ICU >= 59

This works around the C++11 requirement of ICU4C >= 59,
resulting in
/usr/include/unicode/umachine.h:347:13: error: 'char16_t' does not name a type
and ultimately:
/usr/include/unicode/uversion.h:167:55: error: 'UChar' does not name a type
