[Rd] help("R_LIBS") brings up the wrong help file (PR#10475)

[timh at insightful.com]

Doing
	help("R_LIBS")
brings up a help file (the same one as help(library)),
but the help file doesn't mention R_LIBS.
It does have a link to .libPaths, which does document R_LIBS.

The quickest fix would be for help("R_LIBS") to bring up the .libPaths
help file.
