[Rd] Add .git to SCM excludes for build and INSTALL scripts

[Seth Falcon]

Git is a source code management system like CVS, svn, arch, and
others.  

It would be nice to add exclude support to R CMD build and INSTALL so
that the .git subdir of an R package is handled appropriately.

Here is a possible patch:

diff --git a/src/scripts/INSTALL.in b/src/scripts/INSTALL.in
index 75da9db..09e5ab5 100644
