QtTools: update packaging for RC1
QtTools: update packaging for RC1

Just one change: require new qt5 bootstrap-devel package.

NOTE: the build does not work properly yet. Compiling errors out when
using 'Qt5Bootstrap.a' as a link target, due to the path being empty.
This may require another round of FOOdir modifications/additions to
qtbase.
