graphics/librsvg2: build fail using WITH_MOZILLA_PLUGIN

[barbara]

Trying to install librsvg2-2.26.0_2, I've got an error using WITH_MOZILLA_PLUGIN. Without that option it builds as expected.

It seems that the path after "-rpath" is missing.
Looking at the differences between Makefile.in.bak and Makefile.in in work/librsvg-2.26.0/moz-plugin, I think the the problem is the removal of the inclusion of Makefile.webplugins, because ${WEBPLUGINS_DIR} would be "" in post-patch phase.

So this could be the patch:
