qdoc: Fix output file name generation for examples

When generating output file names for examples, qdoc prepends
a module-specific prefix. Unless already defined, it defaults
to the project name defined in .qdocconf file. This leads to
wrong prefix being used in some cases - specifically, on pages
in qtdoc module listing examples in other modules.

This change takes the modulename prefix from the node, and
only uses the project name as a fallback.
