According to be5adb92b5c4d5d95e5089be94c706b930fea7ba, the UploadDir
method supports two ways of copying depending on whether a trailing
slash is used:
src = "dir" -> dest/dir
src = "dir/" -> dest
On BSD-based systems (such as OSX, FreeBSD, etc.) the `cp -R` command
handles these two cases automatically. However, Linux treats "src/" and
"src" the same.
To support the trailing slash syntax portably, we can use:
src = "dir" -> dest/dir
src = "dir/." -> dest
This works on BSD and Linux. It is better than using wildcards as it
grabs hidden files as well.
This fixes#1196 that prevents the chef-solo provisioner from working
with the chroot builder.
