Use existing rtl_str_toInt64_WithLength

...like it is also already done in LineParser::readInt32 in
sdext/source/pdfimport/wrapper/wrapper.cxx (esp. since the code should be
changed to use C++17 std::from_chars once that is available in all our
baselines), reverting again the introduction of rtl_str_toInt32_WithLength in
b1df9c67349cf4cc5be4128d797aefb87f50e38f "[API CHANGE] reduce cost of numeric
conversion"
