Hide bundled Python from linuxdeployqt to avoid scipy/libgfortran scan failure

linuxdeployqt recursively scans all .so files in the package tree and
fails when it encounters scipy's internal libgfortran which depends on
libquadmath. Temporarily move lib/python/ out of the way during the
linuxdeployqt step and restore it afterward.
