[oe] [meta-qt5] qtwebengine link errors agains icu

[Lerner, Dave]

On branches jethro and jethro-next I get several link errors building qtwebengine like:
...
qtwebengine/5.5.1+gitAUTOINC+qtwebengine_146ebe26dc-r0/git/src/3rdparty/chromium/ui/gfx/render_text.cc:1186: error: undefined reference to 'icu_52::UnicodeString::UnicodeString(unsigned short const*)'

...

My local.conf includes
MACHINE ?= "qemux86-64"
PACKAGECONFIG_pn-qtbase_append = " accessibility"
IMAGE_INSTALL_append += " qtbase qtbase-fonts qtbase-plugins qtwebengine"
PREFERRED_PROVIDER_jpeg = "libjpeg-turbo"
PREFERRED_PROVIDER_jpeg-native = "libjpeg-turbo-native"

This bug is referenced upstream in Task-number: QTBUG-49693 and the bug is already fixed in the repo referenced by the meta-qt5 recipe at  git://github.com/qtproject/qtwebengine.git commit 1847e158e09e24af704b02c8fb30adbf04d3befa branch 5.5, 17 commits after the current meta-qt5 qtwebengine_git.bb SRCREV_qtwebengine = "ce095e94b6861".   

The change below corrects the link issue.
