Patch for the emerald.spec file

Description of problem:
The rebuild of the source package fails with mock (for i686 target).
The libXres-devel dependency is missing in the build requirements.

Version-Release number of selected component (if applicable):
emerald-0.7.8-1.fc10.src.rpm

How reproducible:
$mock --init
$mock --rebuild emerald-0.7.8-1.fc10.src.rpm
  
Actual results:
...
checking for EMERALD... configure: error: Package requirements ( xrender >= 0.8.4  		    gtk+-2.0 >= 2.8.0 		    libwnck-1.0	      		    libdecoration     		    pangocairo) were not met:
Package xres was not found in the pkg-config search path.
Perhaps you should add the directory containing `xres.pc'
to the PKG_CONFIG_PATH environment variable
Package 'xres', required by 'libwnck', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables EMERALD_CFLAGS
and EMERALD_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
