Patch for print/cups-base/Makefile

Bug in print/cups-base Makefile. Around the time of CUPS 1.4, the build was changed to use xdg-open command, when available, for the web interface. At that time the default command in desktop/cups.desktop.in was revised to use a variable controlled/set by the configure script. The configure script was revised to check for the existence of the xdg-open binary on the system an set the variable to either htmlview or xdg-open accordingly.

Since this ports source change, the Makefile line to edit the cups/desktop.in prior to beginning the build is non-functional.

.if ${PORT_OPTIONS:MXDG_OPEN}
        @${REINPLACE_CMD} -e 's|htmlview|xdg-open|' ${WRKSRC}/desktop/cups.desktop.in
.endif

The use of xdg-open (devel/xdg-utils) is specified as a run time dependency and will only be built, if not already on the system, AFTER cups-base has been built. It is hit or miss whether xdg-open is actually used as configured. It will never be used when built in a poudriere jail.

A quick patch to the Makefile has been prepared to revise the edit line to replace the configure variable - @CUPS_HTMLVIEW@ - and is attached.

A more proper fix would be to revise xdg-open from a RUN_DEPENDS to a USES dependency.  That of course would require additions to Mk/Uses/
