xmloff,filter: Flat ODF import: import BuildId from meta:generator

The problem is that SvXMLMetaDocumentContext::endFastElement() works to
init BuildId property for ODF packages but not for flat ODF files
because the entire content of the document is inside that element.

So init BuildId when the office:meta element ends.

Also, add the missing "BuildId" property in XmlFilterAdaptor.

This allows the CppunitTest_sd_import_tests testGradientAngle to work in
the subsequent commit.
