[oe] [meta-qt5][PATCH v2] qttools: fix cmake usage of linguist tools

[Cody P Schafer]

Without this, Qt5LinguistTools/Qt5LinguistToolsConfig.cmake would
attempt to locate lrelease and lupdate under prefix, even while we were
cross-compiling and prefix points at the native system's root dirs.

I'm still not sure this is the right place for this fix because I'm not sure
why it seems like cmake files for Qt5LinguistTools are sometimes pulled from
STAGING_DIR_NATIVE, and other times pulled from STAGING_DIR_HOST.

But at the least this _appears_ to workaround my issue.
