patches/rstudio-server-multi-version/0007-detectRLocationsUsingR-Restore-R_HOME-at-the-end.patch: Replace.

The changes have been rebased on top of version 1.4.1717 and include a
bug fix.  Previous versions would fail to look up the user's active
sessions (and thus fail to restore a previously set version of R) when
rserver did not run as the same user account as the rsession
process (e.g. root).

* guix-science/packages/rstudio.scm (rstudio-server-multi-version):
New variable.
