QDoc: Remove unused variable `sourceFileNames`

When QDoc runs it collects a series of input source files based on
certain configuration variables.

The files are collected into two maps, in `processQDocConfFile`,
`sources` and `sourceFileNames`.

The collected input source files are later used as the base for
extracting the user-provided documentation.

Nonetheless, `sourceFileNames`, which is populated along with `sources`
was never used and is thus removed as dead code.
