common: add qt host binaries to meson cross profile

When cross building 32 bit qt6 packages on 64 bit hosts the qt6 host
tools are not found, because the path is determined via pkgconfig which
points to /usr/lib32.

Adding the required binaries to the cross profile as a workaround to
resolve this.
