Disable /etc/printcap parsing if no PPD file specified

[Ian Pilcher]

I got tired of having my default printer constantly reset to 'lp' and
seeing error messages about not having a default PPD file specified.
This patch checks for a [ppd] section in the Wine config file before
trying to automatically set up the queues in /etc/printcap.

Modified files:
    dlls/winspool: info.c
