LibPDF: Scan for PDF file start in first 1024 bytes

Browse source 
Other readers do this too, and files depend on this.

Fixes opening these four files from the PDFA 0000.zip dataset:

* 0000015.pdf
  Starts with `C:\web\webeuncet\_cat\_docs\_publics\` before header
* 0000408.pdf
  Starts with UTF-8 BOM
* 0000524.pdf
  Starts with 867 bytes of HTML containing a PHP backtrace
* 0000680.pdf
  Starts with `C:\web\webeuncet\_cat\_docs\_publics\` too
