Fix invalid Qt prefix version when looking for HostInfo module

Browse Source 
In QtSetup.cmake the PROJECT_VERSION_MAJOR variable was used to
identify prefix of 'Qt<version>HostInfoConfig.cmake'.
Qt<version>HostInfo is not found, if project version differs
from qtbase version.

Move the 'INSTALL_CMAKE_NAMESPACE' and 'QT_CMAKE_EXPORT_NAMESPACE'
variables to 'QtBuildInternalsConfig.cmake'. In this case
variables will be exposed for a wider list of internal routines.

Use the 'INSTALL_CMAKE_NAMESPACE' variable as prefix to find
Qt<version>HostInfo module.
