[Rd] GNU tar does not ignore files in .Rbuildignore (PR#1339)

Putting patterns in .Rbuildignore has no effect when the tar being used is gnu
tar (1.13) on solaris 2.7, whilst /usr/sbin/tar works perfectly.

TO REPRODUCE:

The current directory contains a source package directory ./mypkg...

bimini.jgi-psf.org% echo >mypkg/foo
bimini.jgi-psf.org% echo "foo" >mypkg/.Rbuildignore
bimini.jgi-psf.org% R CMD build mypkg
* checking for file `mypkg/DESCRIPTION' ... OK
* preparing `mypkg':
* checking whether `INDEX' is up-to-date ... NO
* creating new INDEX
* removing junk files
* building `mypkg_0.1.tar.gz'

bimini.jgi-psf.org% gzcat mypkg_0.1.tar.gz |tar tf -
mypkg/
mypkg/DESCRIPTION
mypkg/R/
mypkg/R/First.lib.R
mypkg/INDEX
mypkg/man/
mypkg/man/First.lib.Rd
bimini.jgi-psf.org% setenv PATH /usr/local/bin:$PATH
bimini.jgi-psf.org% tar --version
tar (GNU tar) 1.13

THE PROBLEM:

The exclude file produced by build and placed in /tmp/Rbuild.$$ contain file
names of the form mypkg/xxx, where mypkg is the package directory and xxx is the
path name relative to mypkg. This is the format accepted by /usr/sbin/tar,
whilst gnu tar expects patterns without the preceding package name mypkg/.
