Pasted-in document need only be opened for reading

Otherwise, if SRCDIR is a read-only tree, CppunitTest_sw_rtfimport would fail
with the

CPPUNIT_ASSERT_EQUAL(ERRCODE_NONE, pStream->GetError());

from <https://gerrit.libreoffice.org/#/c/51992/> "Check successful stream
creation".  (And before that, it would have more obscurely failed with the

CPPUNIT_ASSERT_EQUAL(2, getParagraphs());

in testTdf90260Par failing with 1 vs. 2.)
