Set R_LIBS_USER='' in dependent build environment (#31287)

Browse source 
* Set R_LIBS_USER='' in dependent build environment

Despite R packages being installed with the --vanilla flag, which
ignores Rprofile and Renviron files, R will still set R_LIBS_USER if the
default directory exists. This could lead to pulling in packages from
that directory during the build which could cause the build to fail. To
avoid that, explicitly set R_LIB_USER='' to ensure that packages from
the HOME/R directory are not in the library path.

* Update var/spack/repos/builtin/packages/r/package.py
