[R-sig-Debian] Install R on Ubuntu with libcurl support

[Michael Coyne]

The one strange thing I am now noticing is that precise does not have
libcurl listed as a dependency. If you go to
https://cran.r-project.org/bin/linux/ubuntu/precise/Packages and look
for "libcurl" it is not listed. The other Ubuntu builds, such as
trusty or wily do list it.
